I followed some of your advice from pervious videos and managed to reduce my hot water gas usage by quite a bit so I thought I'd share those tips in my own video a few weeks ago. It's became somewhat more popular than I expected though, and then I started getting loads of people complaining about my flow temperature and legionella advice! I'm very glad that I can point them to videos like this from true professionals to confirm what I say in my own video. A lot of them still don't believe me though and they get really angry! Oh well. Modern internet, eh? Keep up the excellent work.

Good advice but also insulation is good. I topped up the loft insulation several years ago from 4" when I bought the house to 12", had double glazing fitted, both while I was working and a new condensing boiler after taking early retirement. Bought pipe insulation for underneath the floorboards where the central heating pipes run in the downstairs front room. I put a new roof on the extension and put loft insulation in with tongue and groove board ceiling. I plan to do the rear kitchen wall like this. I put in a new bath and altered the plasterboard layout so filled the cavity with loft insulation. 15°C in this bedroom with no heating and Sun streaming through the window making a nice almost 21°C in the Sun. Wearing a T shirt, jumper, jeans, socks and bedroom slippers. 3 LED bulbs and some CFL lamps when they were going cheap at 10p each, I guess to get LED ones in stock.

We have no central heating and have an open fire. I have thermally lined the curtains and draught curtains, draught sealed doors and windows ( no double glazing). I have made blankets for every chair and have a strap on hot water bottle over thick jumper. Any plug in heater is only used if washing is also being dried on rainy days- always has to do two jobs. We sit in whichever room washing is being dried! We are old and remember surviving such times in the 50s. Have in the past put newspaper between blankets but it gets a bit noisy!

Thanks Adam….for these helpful videos! 💪

I went up to 55C on the flow temp at the start of October. I base that change from 45C on when the 1 or 2 C lift required in the office in the morning starts to take longer than an hour radiator time. I currently just eye-ball the graphs, but I intend to start recording the actual delta for rooms and at least factor in "demand time per degree delta". What I really need is a gas flow sensor installed to actually monitor the gas usage as runtime doesn't account for the boiler trickery.

Thank you, great resource and tips.

Fantastic video this buddy! Plenty of very useful tips and also explanations of what to do if the alterations dont suit the user! 👏👏👏

IF you can get under your floor floor, buy some insulation for between the joists. To hold it up, simply get some plastic netting , and staple it up to the joists as you unroll it . ( messy job though, but worth it .) You might also want to put a reflective foil insulating layer under your carpets , when replacing them. Buy a roll of insulated foil and slot it behind radiators on outside walls particularly , but also on the room you heat the most , to stop heat transferring to other cooler rooms . Use Pot Lids when cooking, you will be amazed how much you can turn down the heat and still keep a pot boiling you put on a pot lid. Otherwise that extra heat is just heating your kitchen . Turn the heat down on a boiling pot until it just stops boiling, then put on a pot lid, it will start to boil again, then turn it down again until it is just boiling and no more . Remember, the water does NOT get any hotter once it has boiled, it just evaporates quicker ( and so does your bank balance:( Test it with a glass pot lid, it’s easier to see the water boiling . As was stated, put on layers , if you have cold feet , buy better insulating socks, or just wear several pairs. Good luck this winter , we might get lucky and get a mild one .

Good tips! As for keeping feet warm, put up your feet/legs! I've diy-ed a box, put 4 caster wheels under them and put a 50mm thing foam on top. Together with a winter sleeping bag, you can quickly get in, roll the fooftstool under the legs and it'll keep you warm down to 10⁰C! Also, not only wear multiple socks, wear multiple pants, ie put a sweatpants under the trousers for example. Best way to keep warm is putting a cap on your head. 25% of body heat is lost through the head, depending how much hair you have.

Some interesting guides but I'd question the hot water thermo being set at 50 degrees due to storage versus distribution times.

Thankyou . I'm going to share this video big time

Hi, great video as always. BAXI 836 Combi 1 year old. When I turn the hot water temp down to 43° on my Nest thermostat the boiler reading always shows around 10°higher. Why.? Called Baxi technical who stated the combi will struggle to maintain a low temp. Do other boilers have this temperature difference?

Heating engineer and plumber here ….well done for what you are doing 👍 Every house I go into I’m doing the same. Shouldn’t be down to us though as many people needed this stuff from April and government should have been helping improve education around easy efficiency savings years ago ( if thats what they truly cared about 🤔)

I want part 2 with only complicated ways to reduce your energy bills like undervolting your CPUs and GPUs, linking your heat pump to your fridge and freezer to utilise the cold, putting vanta black rugs in front of south facing windows etc

Regarding adjusting your boiler flow temperature to the minimum you can get away with throughout the year, I noticed afterwards you mentioned if you have a weather compensation control boiler “it does all that for you”. I have a Baxi 400 combo boiler with Tado smart thermostat which has a weather compensation feature. What option is most efficient: Should I be adjusting the flow rate manually to the minimum I can get away with (60) with the Tado modulating between a smaller range of flow rates or leave the flow rate at max (80) and allow my Tado to modulate with the full range of flow rates available to it?

In the media, there's a lot of advice about turning off radiators in unused rooms (which on a side note is bad advice because they never state to leave the rad on in the room where the stat is!). Is there a point where this becomes inefficient? Maybe you could do a video on this, for example, turning off all upstairs rads and only heating downstairs (obviously with room stat downstairs)? Love your channel, best I've ever seen regarding home heating. Thanks

It is at least once in a week recommended to push the heat to over 65°C because of legionella, it is dangerous to keep the temperature at 50°C. Thats why seperate heat pumps for your warm water have the legionella mode to heat the water once in a week over 65°.

Amazing vidoe mate

For people with PV, it's possible to install measuring devices that run the boiler to higher temps as long as there is un used PV energy. Saves electricity and most important the tax and transport costs.

I have a question, our entire roof is insulated but the floor between the first floor and the storage area above it isn`t insulated.. Will this have an large effect if I put rockwool between that? The storage area / loft isn`t heated

UK council's made a massive mistake in loads of homes by putting thermostats in passage's, the coldest part of the house so the other rooms are like ovens. Also, some council's say you CANNOT fit draught excluders?

I tried to turn off the pre-heat function on the combi, as mentioned in tip 3. I followed the user manual. A P shows on the digital screen to indicate it’s off, but it still fires up a few times a day including waking me up at midnight 🤦‍♀️ I’ll try it again!

Hi great video. I have a Santon Premier Plus and cannot find the hot water thermostat anywhere? I did lower the temperature for flow on the boiler though.

How do I know if my combinboiler is condensing properly. As I’ve just had flue tilt adjusted

Can all combination boilers manage to reach condensation mode? I've turned the flow temp. down as low as 45 degrees and I still get plumes of smoke from the boiler exterior vent. I have seen it said that no smoke means that it is condensing. Any advice guys?

I have a regular condensing boiler coupled with a boiler mate 2000 - any recommendations for people like me who don't really have access to all the control stuff you stated. Many thanks :)

How does range rating apply (or have a beneficial effect)when you have a modulating condensing boiler (say V200) when weather compensated?

At 1:41: you mention to beware as mixer taps can play up here. Does this also apply thermostatic mixer showers?

I have an Intergas Rapid 32 (condensing combi with no water tank). Set the flow to 55 deg and water to 50 deg. The room thermostat/programmer is halfway up the stairs and set to 18 degrees when called for... programmed to come on at this temp for 45 minutes as we are waking up, 15 minutes when 5he kids are about tobet home from school and an hour after dinner when we relax a bit. We might flick it up to 18 as a manual overide if we are in and feeling chilly. Is there anything else we can do to cut gas use? The loft is insulated well, the house is double glazed, we wear jumpers, slippers etc. Would smart room stats and programmer/thermostat help? Was looking at Drayton Wiser multi-zone. It's just me and the dog at home during the day so only need one or two rooms topping up heat wise on cold days.

Before you put jumper on think about getting bass layer thermals. I have some of those skin tight sport ones they work really well to keep drafts away from waist and sleeves, then if you put a slightly bigger set thicker set over that and then a slightly bigger one again ect, you get 2 or 3 layers in under a normal shirt. Putting larger items like jumper sweater or hoodies on should be later resort as they start getting more in the way of what your doing day to day like the sleeves when you're doing stuff in the kitchen or doing some stretches or exercises maybe. Bass layers feel a lot more casual. Just important to find a material mix that feels comfortable for that first layer and stretches on right.

If you don't happen to have a "Chimney Balloon" handy , old pillow/rags in a plastic sack does the trick. Draft seal round the loft hatch too, often missed out. Thin Reflective insulation stuck to the wall behind radiators if they are on outside walls. ( can be done with rad in position with stick & double sided tape)

At 6:25 with a condensing boiler how do you no what heating flow temperature rate is at if you do not have a dial?

If your combi also runs your shower , turning the water temperature down may make your shower cool rather than hot. But , a SHORT cool shower is good enough , and saves money.

Another great video Quick question on timing hot water. I have always told my customer that if they had a well insulated hot water cylinder that they would be better off leaving the hot water on permanently. As this stops the cooling affect of cold water coming in when the hot isn’t on and cooling down the remaining hot water left in the cylinder. I have a combi at home, so can’t test this. But I had asked some of my customer with unvented well insulated cylinder and smart meter to try it in the summer when the heating wouldn’t affect the gas bill and all have said there gas usage is less when it not timed.

When we cook, we put the stove off as soon as possible, then serve the meal and draw the heat from the remnants of the cooking pan or frying pan and feed it into our central heating through a custom build system. Fully cooked food contains an enourmous amount of heat and Joules that can be drained.. The suction system, we actually catch that heat to use again and circulate it..

The only issue with this is the ACOPL8 states that stored water (water tank), should be stored at 60°C or above to prevent Legionella bacteria growth. Obviously, most domestic properties have enough turnover of water daily to prevent any growth buildup. But, if you leave your home empty for any particular length of time, I would fully recommend pasteurising your system (turning up the boiler and cylinder thermostat to maximum to ramp the temperature right up to kill any potential growth in the system). I will be following the advice given here and hopefully saving myself a small fortune over the winter months, I am even building some terracotta room heaters to place strategically around the house to get some cheap off-grid heat 👍🏻

Ok, here’s my question:- I would appreciate any well thought out response. I live in a very well insulated, ground floor apartment. The apartment block is new build, or at least it was when I moved in, 9 years ago. The building is gas free! My apartment is fitted with storage heaters and I subscribe to an economy 7 tariff. I understand fully the principle and pros and cons of storage heating. The main issue is that in order to maximise the efficiency of storage heating, you need to be a first rate weather forecaster. You need to know tomorrow’s weather in order to correctly set up your heaters the evening previous evening. I only have 1 storage heater permanently running during the winter months. It is located in my hallway, which is 10 feet wide and 25 feet long. My lounge, kitchen, bathroom, utility room and 2 bedrooms all open into this hallway, as does my front door which opens onto the street. If I leave all internal doors open, that 3kw storage heater is usually man enough to maintain the whole apartment at a comfortable temperature. But sometimes additional heat is needed. I don’t employ any of the other storage heaters, they are too slow to react. As a back up in my lounge I have a 2kw dry core radiator. In the large bedroom a 2kw oil filled radiator. In the small bedroom 12 feet by 11 feet I have a 0.6kw infrared panel and in the bathroom a heated towel rail. Both radiators have an independent thermostat and a separate power control which can be set for 0.6kw, 1.4kw or 2kw. I tend to leave them both set to 0.6kw which would appear to be sufficient to maintain the required temperature. Obviously the thermostat is clicking on and off. If, I were to leave the thermostat exactly as it is, but adjust the power control to a higher setting, would this make my radiators more efficient as I will be reducing the amount of time the thermostat is on, as the higher current will cause more rapid reheating. Your thoughts and comments would be appreciated.

Tip no.4 flow restrictors...it's a no no for combi boilers,if you have low flow,and non condensing boiler(and even on condensing boiler sometime).the control of hot water will be difficult the boiler will shut off and on,and the water will be too hot then too cold.taking a shower in this condition....

If by setting your boiler flow temp to low temperatures (below 45c) the boiler spends a lot of the time cycling on/off the lowest modulation rate (small house installed with a fat combi boiler for hot water), is this more efficient than just running your flow temp around the min modulation rate (~45-50c flow temp... small rads).

@HeatGeek

The lower the temperature the more efficient always. Lower temps means less cycling as it modulates down earlier. Cycling o ly accounts for 1% effy reduction on modern boilers anyway

If I want a higher flow on my shower, there is a point in blending 60C water with cold, isn't there?

Is it advisable to always leave your water heater on? I'm having to reheat water every time I need to use the shower and its becoming annoying as its very expensive. For me to get hot water, it costs about £1.75.

That’s very expensive. Are you using gas to heat the water, or immersion element? How big is the tank? Mine cost about 40 pence or so, from room temperature to 50 odd degrees

The Testo pipe thermometers are accurate to within + or -1.3 degrees Celsius. Says it inside the box.

Can Legionnaires actually form in a dark airless tank? Just wondering as I’ve only seen it in open water cooled AC systems.

Potentially but the water would have to not move for weeks on end.. maybe years

That’s the reason I wonder why it’s often mentioned, it seems very unlikely to me tbh.
