Hot water cylinder alternatives

clockworks_2

I don't have gas so can't get a combi boiler. My hot water cylinder will need replacing very, very soon and am exploring alternatives out there.

Is there anything better that runs on electricity that is more efficient?

thanks

All electrical appliances are about the same efficiency. Do you have central heating. My preference on your case would be a new larger tank highly insulated with a immersion heating element.

Advantage of using a hot water tank is that you can heat the tank up with the immersion heat with the cheaper economy seven electric at night. Then it will store the heat in the tank till its needed. Unlike other forms of storage heating that just kick out heat all the time.


I would also have a two spare heat coil for further expansion such as solar panels/ air to water heat pump/some other form of oiler(lpg,oil,solid fuel). Depends on how space you've got.

That presuming you've got wet central heating

Hi mankysteve, I live in a flat that has only electricity. It has an air source heat pump for the heating and cooling, but a hot water tank for hot water. I wanted something that gives me hot water on demand like a combi boiler and more efficent. I don't have central heating

dont have one at all. you should only heat the water you actually require. esp with expensive electric heating.
never use a bath, use an electric shower only. use a water heater for washing up water or use the kettle.
as below.

I would rather have something that replaces the cylinder in my airing cupboard. Having to install thoses in two bathrooms and a kitchen would look hideous! And then i would need to install two electric showers too!

if you are all electric, you should have electric showers fitted by now!
probably pay for themselves within a year.

I think you're right, but i need a solution as i have a bath, 2 showers and 2 sinks that need hot water. (not all are used at once)

clockworks_2

any other suggestions?

Does the Air Source Heat Pump not do the HW tank as well? It should do.

no mine is purely for heating and cooling. It's not a ground source one, a lot of air source just do heating and cooling.

You can bigger instant heating boilers bt they won't be big enough to feed mixer showers.

My preference would still be to have a new as big as you can fit well insulated hot water tank with a immersion on economy seven.

With instant heating your talking 13p ish a kilowatt with a tank on economy seven its reduced to 5-7pish a kilowatt. Modern tanks leak very little heat.
