Economy 7 heating. Wet radiators

Plantaholic_Sheila

We have a 26 year old GEC NIGHTSTORE.
(Hate nightstorage room heaters. Gas was not an option. Did not want oil.)
It is wonderful.
In our highly insulated home it heats special bricks on cheap rate, night time energy. It then tranfers this heat to wet radiators, only when needed.
It is quiet.
It can be left safely if we are away.
Unused heat is kept in the boiler for another day if the weather is unexpectedly warm.
It is very cheap to run.
It is not complicated.
We love it.

Now planning to moving to a small new build well insulated home,
we want another identical system.
But sadly GEC NIGHTSTORES are no longer made.

As we are getting old, I do not want to worry about log burning stoves/ bio mass boilers/ complicated ground source technology.
Just something simple that will work even if we are a not at home.

Is anyone in the world making a similar product?
Help please.
Thanks.

One possible alternative here more detailed specification here

I had already found the site you gave me link to.
However this system is very different. It is just a wet system.

I find it hard to believe that one tiny pressurised tank of very hot water can run radiators all day on just 7 hours charge of cheap rate electricity.
It uses 28Kw electricity per hour.

Will investigate it in more detail to see exactly what is involved.

Thank you espresso.

The usable energy stored by the largest version of this boiler is about 30kWH. This would be about sufficient to heat a flat in winter or a house in spring and autumn. You always have the option of topping up during the day. Of course that same number includes your hot water and you could use half of it on a couple of large baths. The smallest version is a little over a third of the size and it would struggle to heat a small flat on stored water. The power of the boiler is entirely sufficient, it is just limited by the storage capacity. There are also larger versions, but realistically they are for a hotel rather than a house. Do you still have no gas supply?

What you are referring to is the expansion vessel, not the heating circuit.

If not in a mains gas area, whole house heating is not cheap, even at electric off-peak rates. What is your objection to an LPG fired wet system?

We have had a Nightstor 100 electric boiler for the last 25 years since moving in. Very economical, but sadly not in production now. The next best bet would be the electric radiators independently sited, without using a boiler, which charge up overnight on cheap rate Economy 7. Do you know of anyone who repairs or deals with these boilers, just in case we need them, we are in the Essex area.

If you search GEC NIGHTSTORE on www there are many sites listed as being able to fix them and have spare parts. I am sure there must be one near Essex.
