Conservatory Heating

[con1_uk]

Evening all,

We are in the process of having our conservatory built, the current plan is to have a portable heater but the more I read the more I doubt this idea.

The finished conservatory will be 4mtrs out and 3.8mtrs at its widest, Left hand wall will be complete brick, the end wall will be external bi-fold and the right hand wall will be partly existing wall (kitchen) and a small dwarf wall with "A" rated window. All glass will be "A" rated and the roof will be blue glass with temp control, basically a lot less glass than a standard conservatory (or Orangery as the missuses calls it...), the new room will be separated by another set of bi fold doors.

It will face East.

What is the best heating system (within regs) and if we go for a portable one how do I spec it please?

Or

Do we have the central heating piped though and get the rad TRV and timer controlled?

Or

Wood burner?

Thanks for reading so far.

If you calculate the heat loss you will find that when its -2 C outside as tonight then you will need about 8 kW and that will cost you about £1.50 an hour with electric and about £0.60p per hour with gas.

Why would you want to use it during the winter?

Thanks,

how do you calculate heat loss please?

Also

How much are Air to Air heatpumps and how much are they to run please?

Prices for fitting airsource heat pups vary depending on the type of installation, location of the out door unit and if you fit high wall or low walll units

Typically about £1500 to £2500.

Trouble is their efficiency and heat output fall off very seriously when its -2 C outside like tonight which is just when you want the most output!

I agree 100%👍👍

Heatpump or woodburner. Heatpump is likely to be cheaper.

You can't have radiators in there connected to your heating system no matter how many valves/timers/thermostats etc you put on it - building regs banned this a couple of years ago

By far the cheapest is a mobile calor gas heater!

About £100 I expect.

Then you will quickly realise just how expensive and wasteful heating a conservatory in winter can be.

They are for April to September use!

These DIY fit units are a piece of cake to fit. You don't even need to pull a vacuum to gas it up.

Tony is right as normal, the COP drops away when the temperature drops, but normally that's only a few days a year. From personal experience, a wee split unit will drop to about 1.5 COP on the coldest day & that was with a standard not invertor unit.
