new house heating system mind boggling

Is there some kind of service to pay for someone to come round and explain how everything works ?! And set it up

I am in a right mess .

We have a boiler and an immersion tank .

Turned the tank off as this is what it said online to due to costs however now the boiler is only giving limited amounts of hot water ... enough for one shower .. not a full bath full

Any bright ideas anyone?!

That's why my electricity bills are high! The showers for 4 people and the washing machine

Show quote history

I find my washing machine only runs the 3kW heating element for about ten minutes per wash, so not very expensive. The churning motor and pump use little.

A shower will use around three or four times as many watts, for as long as the shower lasts, so quite a lot more.

The tumble drier is expensive because it can run for an hour or more, depending on the load.

Oh that thermostat takes me right back. We had that until a couple of months ago, set to 19 in the winter. Now have hive.

Our system lets us heat hot water only (as in independent of the central heating )but the bathroom radiator comes on too, it's some sort of overflow thing for the hot water only system. So when it's too hot to want the bathroom radiator on (like in Summer) we turn the boiler off altogether and rely on the immersion for hot water. We can also, if we want, have heating only, independent of the hot water. We sometimes use this if going away to prevent the house getting too cold and to avoid frozen pipes.

The immersion heater is much more expensive to run than a gas boiler for hot water.

A radiator is only needed as a heat sink if you have a coal or wood burner which does not turn itself off when the water is hot.

If you have a gas boiler and a warm bathroom radiator it has probably been deliberately plumbed that way to warm or dry your towels. This is a very good feature. You can turn off that radiator in summer if you want

I think the thermostat with the dial might not be connected to anything, it looks quite old.

I recently had a new boiler and they removed the thermostat like that and put a plastic cover, but it could have just been disconnected.

My new boiler is a combi but my old one the boiler heated the radiators and the hot water in the water tank. I also had an electric immersion heater in the water talk which I never used, but was there.

You need to find out what temperature your boiler is running at.

wardgas.co.uk/hot-water-cylinders/

If you use the link there is a simple diagram of how the two work. The Calorifier is basically a pipe that takes hot water from the boiler and spirals through the hot water tank. It's possible that it only coils around part of the tank so it takes longer to warm the entire tank.

Thanks this is very helpful

I think it is as there's no option to pick temperatures on the screen thing.

Can you install hive yourself or does a person need to install?

That’s a Honeywell system by the looks of it, we have similar.

Have you checked whether you have temperature valves (TRVs) on your radiators and if so what they are set to? Might be set too low

It's worth knowing that your boiler can't heat the radiators and the water at the same time so if you were 'blasting' the thermostat up to warm the house at the same time as you ran the bath, the boiler couldn't replenish the hot water iyswim?

I dint think this is true. Some systems don't let you have the hot water on unless you have the heating on at the same time

My hot water is on for 1 hour in the morning and the heating goes on at the same time but is on for longer.

Surely they are broken then, otherwise how do you get hot water in summer?
