Thanks, so yes we could easily be spending £2 a day on dehumidifiers which is £60 a month! They're not old but they're not top of the range ones either. I'm gonna stop using them for a while, they don't completely eliminate the silverfish issue anyway.
The issue with TRVs is they are expensive to buy already aren't they? So you have to speculate to accumulate I guess.
How do I make sure boiler doesn't have pre-heat hot water enabled? Its a newish Vaillant combi, does that matter? Thanks in advance.
It will be in the boiler menu, it's something like preheat hot water just have a browse around. If it's on it keeps some water hot at all times ready for use but it hardly saves any time but costs a lot to have on
Also as it is a combi boiler, make sure your water and hot water are not set too high. You can adjust the knob and then see how it impacts your hot water tap temp and radiator temp, many have eco settings on the dials. My girlfriend used to run a boiling steaming bath then add loads of cold water to get it the right temp as hot water was set to max on boiler - waste of money. Just reduce temp and then try furthest taps to make sure they're getting hot enough.
A recent report found that turning down the flow temperature on your gas boiler can save 9% on your gas bills. We show you how.
TRV's can be had for £8-12 each but prevent you earning up spare bedrooms etc or roooms basically heating up costantly, without them you basically demand heating to each unlocked radiator. With them, that rad will close off once temp is achieved reducing the energy use of your boiler. They'll need fitting but will last for many years and change how your heating works. We didn't have them in our old house and the heating was either off or on and you either locked the rad shut or it was on, again huge waste of money for spare rooms and the like where you can set to frost or 1.
Likewise having your thermostat in hall, if that says 17.5 so boiler fires up as you've got it set to 18, it'll stay demanding heat. If you have thermostat in a habitable room like living room, when that room is at temp it will stop demanding heat and turn off
