Electric heat only boiler installation advice for a charity please

Estimated 24kw heat loss going off your room sizes

You've come on a public forum and asked advise, you've been given that advise by people from all areas, be it oil like myself and a few others, to mains gas, lpg and electrics. Of course you're going to be given plenty of options because like I said this forum is full with specialist in different areas.
I'm not being nasty in anyway, I'm just saying people gave their opinion based on what you asked.

I understand that, and I appreciate it. But you must also understand that you are not dealing with a moron DIY enthusiast here.
In real life I refurbish properties, commission trades etc. and therefore I do have an idea of what I’m talking about.
I look at everything from all angles, and I’ve already had to discount the use of the oil system after considering all alternatives.
We’ve already taken into account the fact that if in future the landlord decides to meter our electricity supply we may at that point have to then make a decision to change the electric boiler to LPG - in which case the plumbing will already be installed - we may even be given an LPG boiler in a few months. But in the meantime we need a means of providing heating.

Thank you, based on what input? We’re aiming for proving a basic level of minimal background heat throughout most of the building.

So will a 12KW boiler be sufficient?

no would need two at the min
so min 100 amps just for them

Mr fibble, to be honest, if you new what you were doing you wouldn't be on here.

People trying to help and you get arsey.

Are you basing that on heating to domestic comfort levels? We don’t require that sort of temperature to be maintained.

room temp of 18dc at -10dc outside

I’m struggling with that calculation, on the basis that a 12KW boiler is sufficient to heat a 3 bedroom house in real world tests?

Here’s the old oil burning plant. Does anyone fancy recommissioning it? We will also need a tank if it’s to run on oil.

Mr Flibble,

If you are looking for a low level of heat what about an air source heat pump either air to water or air to water to warm air.

I appreciate that the costing side may look high at first glance - but there is quite an extensive array of grants and Govt. funded support available to at least look at the feasibility of a scheme.

Lowcarbondorset advise Charities on the support available for such ideas. They only cover Dorset, but could probably direct you to a sister organisation that covers your area. They very knowledgeable of both the funding available and how to capture it.

We recently installed a secondhand 13KW ASHP, driving a ducted air system for a charity in Kings Langley. The design was to heat an archive of training records to 15 degrees.
