cost effective options to heat a small temporary space.

[speedystu]

Hello

I hope everyone and their families are ok at this time.
During my own self-build (mostly diy)
I have to build a small living space (in a garage) two-story for myself and my family of 5 for 1- 2 years before I finish the full-size house. it is temporary but will be approx 30sqm meters downstairs with a concrete floor and upstairs 20sqm two small spaces on rafters and plywood. total of approx 50 sqm. it will be a very nice looking Georgian inspired build and a garage that matches that. It is in the countryside.

I have a general engineering and family building background.

What I do have is a sewage system, water and electricity (220v grid).

My questions is, what is the best way to organise cost-effective and efficient heat for underfloor heating and hot water for lots of showers and hot water in a few sinks.
I want to be able to have full-timer and online and phone control capabilities.

I don't love radiators myself and underfloor seems to way to go downstairs I currently use a coal stove to heat large parts of a house, I could do this again but I am open to solutions using electric heaters immersions and solar any other machines and devices I don't know about. Heat pumps likely not be cost-effective. I will be adding full insulation to the space. The solution needs to be cost-effective and use off the shelf items. Currently, weekly costs for electricity and coal is approx 50-60 pound These are the running costs. I want to beat that if I can. I don't think I want oil.

Any advice or ideas appreciated. I will be using registered plumbers and electricians where needed.

It would be great to know some of the options out there.

Keep safe all and thank you.

I really need a heated workshop and possibly an office away from the kids, I could buy some fancy cars to park in there once done although they can stay outside , i can share some pics when it's finished, it'll be very nice temporary accommodation as we don't know how long we'll be in there, maybe 1-2 years hence the need to get the heating right. I have to concede some of the pics on Pinterest of interiors etc are unreal have to think about different ideas and once I have approval from herself, I aim to fit it out nicely. we can then repurpose after to what suits at the time. I think the heating will be needed whatever happens. thanks again all.

How much per month is somewhere really nice to rent in your area?

1-2 years is not a long time and the amount of money you would waste doing it, to rip it out and re-purpose it could possibly be better spent renting and doing everything the way you want it 1st time, with a bigger & better temporary accommodation to boot.

Thanks for that

Been renting for a while . Any changes needed won't be too significant, I look forward to getting stuck in in my spare time. Have some old skills and some new ones, it'll be grand. Thanks you and everyone for the advice.

Have a good one, why would a kettle work on one set of double sockets in a kitchen but not the other but the other will allow a hoover to be turned on ?

Hi all

further to the same requirements above, I came across this idea instead of a heat pump, to me, it seems it should work well and would be a lot more cost-effective for me, an electric immersion heater connected to a circulating mixing valve and fed to underfloor using a standard ufh manifold? making sure correct temperatures were in the line.

Any thoughts or opinions on this? Like can it work reliably in The UK and Ireland?

Has anyone see anything like this in domestic or industrial?

I know this is a mix of plumbing and electrics?

The above will not give you the efficiency of an air source heat pump, you would be better off with a purpose made domestic Electric CH boiler.

Thank you, on first glance, thats a great idea the
domestic ch boiler, its cheaper than a heat pump but If this system can work even with being less efficient it can be cost-effective for me.
The new building this is going in will be close to airtight and have lots of insulation.

Thanks again

Electric System Boiler COLONEL 14kW, Single Phase

Electric boilers are perfect alternative to heat pump and its back up once installed together. As

culmstoreseltermltd.co.uk

is this something like your talking about?

 

[Mike Johnson]

Yes something like that, but make sure you size it properly they come in much smaller kW's as well, if your place is well insulated it may be more efficient to use a smaller size, but don't forget to ventilate as well, to help prevent damp and condensation.

Thanks very much, mike for this info, one last one, do you know if these electric boilers are very noisy? Can you put them in a living space?

 

[Mike Johnson]

They make about the same amount of noise as an immersion heater, not very intrusive, but it depends on the ambient noise of the room, if you have the TV on you will not notice it, but if you are sitting quietly reading you may, the pump makes more noise than the boiler, so that needs careful consideration on mounting and position.

Thanks,is that is the manifold pump you are talking about or the whole boiler?

Boiler pump, these systems are not generally used for UFH, but for radiator systems, I can's see why they can't be used that way, the mixing of the boiler water to cold water to maintain the correct temperature in the pipes (approx 45deg) would need careful adjustment as it would with a conventional system, you will need a large diameter by-pass to prevent local overheating, are you going to use the boiler to indirect heat your water.

I will work with a local plumber to get it all right but looking at the auto mixing valves on the manifold seem like the perfect way to keep the temperature regulated for ufh, the boiler would heat the water for ufh but , I suppose if the boiler was big enough it might be able to heat hot water for separate storage too? I really only had the immersion heater in mind before you told me about electric boilers thank you! I got quotes for heat pumps, they are too much for this budget build first up.hence trying to think of a civilised and budget way around it. Heat pump in the future just not yet
