Very sensible advice, I live in an old 13 room victorian house I run the boiler 24/7 rooms at < 18. C and the boiler flow at 45C there is no steam/condensing vapour visible from the flue the boiler is a Valiant and modulates to a low idle, the pump is running more but that has been doing so for ten years and is still a happy pump. By keeping the house walls at a steady temp water vapour does get absorbed only to be evaporated when the room is heated again which actually drops the wall temperature due to evaporation. Also as the rooms are at the same temp you can reduce the temperature as you don't feel any difference moving around the house. Most houses heat yoyo's all over the show and is shut down at bed time so more energy is thrown in to bring it up to comfort levels in the morning. It takes a week to get the house walls / mass at a steady temp but once there it is worth the savings. Also check your shower head is not high flow, this is wasteful change to a fine jet which will do the same job but 40% less water deduct the kids pocket money for long showers and draw curtains it helps. If the humidity starts to rise I run Ecoair 122 desiccant dehumidifiers on low, the condense 4 ltr over 8 hours but also release 380 watts of heat in the room I also have one int eh bathroom to recover the heat from water vapour or drying clothes, DON"T dry clothes on radiators or let bathroom or kitchen steam in the house either condense it or let it out. Hot water is the killer if the pressure or flow is to high and generally it is. Adjust this so the boiler reduces its burner down a touch makes for big savings also turn the Hot water down to 50 if short runs of pipe 55 if not. I know the recommend temp is 60 + for legionella but too be honest this is very unlikely to exist in a home and if it was present is in a loft tank or unused shower head. Thanks for your tips they are helpful and practical.
Thanks for a very detailed view of your home which is amazing. You must have done a lot of research to get to that high level. I grew up in a Victorian house in the 50's love the big rooms and so many of them, I also remember how cold it was until I learnt to install some rooms with a boiler and rads in the mid 60's the heating the rest had a gas or coal fire. All the best George 😍👍
@@mrcombiBedford Thanks George, yes it is a bit big for one chap and his dogs but I count myself very fortunate. As you know from your years of experience installing and running boilers understand how the house uses the heat and managing it is important my main focus is to control the humidity to below 65% to keep the walls from cooling. A low temperature in the house will encourage condensing of vapour into he walls even worse if they are lime mortar so I have the house at a steady temp all the time. 18C is actually a tad warm for me. Thanks for your very informative videos I and others appreciate the time you take and your relaxed style of presentation. Best
Wow. 13 rooms is a lot to deal with. Great that you have taken humidity into consideration. Very interesting and thanks for sharing your experience 👍
Hi Gary, Thanks for the comment, 13 rooms is a challenge, enjoy 🤩👍All the best George Staszak

@@WOFFY-qc9te Thanks for that, I enjoy helping others much better than day time TV, regards, George
