Heating Hot Water Summer

[postman44]

Am home all day what hours should I have my boiler coming on in the summer to heat my water please.

[malagabob]

As much as you did summer last year maybe.

I live alone and heat my tank only for bath water. The shower is electric, and I have a washing machine.
For all other hot water I heat the electric kettle.

Do you use the bath or the shower? If only the shower you could turn-off the hot water as the washing machine will only use cold.

Got big problem with water/heating! A week into lockdown we noticed that when the water was on, the heating came on too, even when switched off! You can imagine how difficult this was in the warm weather. If we just leave it with the water on, it all goes into the radiators and hardly any hot water. Rang Corgi who said they are only coming out for leaks until after the lockdown!
We are now trying to put them on together in the early morning and late at night.
Usually at this time of year we only have water on an hour twice a day. God knows what the bill will be!

summer and winter we have ours on 6 to 9am and 5 to 8pm

Surely that depends on how much you use it and is it running out? 2 of us in the house now working from home but we're not using any more hot water than normal - ours is set for water heating for 2 hours every evening.

carole - it sounds like your diverter valve is stuck. If you have a system with a hot-water cylinder, rather than a combi-boiler, there will be a diverter valve close to the pump which switches the water flow from the cylinder to the radiators. You can usually move this valve manually to make the water flow through the cylinder.
If you have a combi-boiler I can't help you as I know nothing about them.

We use very little hot water as we have cold fill washing machine and dishwasher and an electric shower but of course we still need some hot water. I have my immersion on for 45 minutes every night and still have hot water when I go to bed. I believe (but don't actually know) that this works out cheaper than boiling the kettle for the mop bucket and other necessities and it doesn't use so much electricity to get back up to temperature as it would use if the water in the tank was cold. The immersion cuts off when the water reaches temperature.

Carole, can you turn the heating thermostat down, or turn off the radiators, manually?

[gingejbee]

Impossible to give a useful answer because we don't know how you use the hot water, when you need it, how much you use etc.

[carolegif]

Thank you for your help bhg. We have a normal system. Will despatch husband to look at the diverter.
Tilly2, we have turned down/off, most of the radiators, but two in the hallway have no thermostats and are stuck solid. Thank you.

What sort of boiler do you have?
If you have a combi boiler and are home all day you don't need to set a timer. Either leave the boiler on -it will come on for short amounts of time to heat the small amounts of water in its tank -around 10 litres - or turn if off and only turn on about 10 minutes before you want to have a shower or put the washing machine on. I've tried both methods and now just leave it on -its not like its using loads of fuel to heat a huge tank. Ignore this is you don't have a combi.

^^^ I've just had another though -it depends what fuel you are using. Ours is oil so may be very different if you are using gas -sorry.
