Attic - second boiler?

[dewsbury]

Hi,
I have 5 bed period house. The heating is from newish boiler that feeds underfloor system throughout. This has worked well for 20 years.
OUr spacious converted attic is well insulated but does not (and will not?) use underfloor heating.
The attic is now used as a bedroom and is cold.

Question 1: Could I get a small second boiler and heat one or two radiators in the attic?
Question 2: What other options (electric?) could I consider to head attic?

If you can get pipework back to the boiler or back to the UFH manifold, I would use that as a source of heat for the attic.

Even if the boiler is set to 45C - 50 C you may just have to oversize the rads to allow for the lower water temp.
Being a loft above a heated area, there are calcs that reduce the radiator size again.

If you can't get back to the boiler or manifold, electric heaters may be a cheaper option than another boiler

My apologies for delay in acknowledging your response.
Thank you for your comments.

I don't think I can put UFH in attic without ripping up attic floor (it's decent flooring in a well converted attic).
Presumably, I cannot use UFH to heat a wall radiator ? The water would not be hot enough??

The thought of electric heating makes me think of long term high bills. I'd sooner pay up front - possibly with second boiler .. dunno!

Attic has a large south facing roof. Would solar heat attic in winter?
So many questions! Too many questions!

Electric rad ?

You can use an UFH heating circuit to heat a radiator.
If you can get back to the manifold you can either add a radiator circuit off the manifold or, if you have a mixing set up at the manifold, you may be able to connect to the higher temp side.

If you do a heat loss calc, you may find that the attic only requires @ 80% of the heat required if located over a heated room - might be less.

I'm with you on spending money upfront to get heating off your existing system, rather than paying for electric heating.

Thanks, I will check with the UFH supplier about adding a radiator.

And if the supplier says no, that’s it? Just find a decent plumber/heating engineer.

Deleted post sorry about that.
