Modern cast iron decorative radiators advice please

[Eyespy999]

Good afternoon all,

I have been to a victorian house that was converted about 18 months ago. A modern boiler and unvented HW system, and all of the house, stripped floorboards have been complemented with modern period cast iron rads.

Nicely looking however the house is like a fridge. Rads are hot and perfoming to temp, but the rooms will not warm up. Mainly radiated head but little or no convection unlike a traditional cheaper panel rad.

My question, is there a way of retro fitting a reflector to the rads to help with radiating heat or is it a rad upgrade to give the customer the room temps they need? I did a calculation using the plumb nation heating wizard and it looks like the rads are a few 000'btu out, but the rads look nice! I have suggested bigger and better rads but they wont be in keeping or asthetically pleasing... Thanks in advance

No and that's the problem with school rads need to be oversized and plumbed as close as possible with 22mm pipe

Have they got insulation in the property?

What type of windows do they have?

Victorian terrace, modern sash with double glazing. House either side. Even with my eyesight I can see the rads are not big enough to heat the room.

Shaun - without lifting the lovely wooden floor I cannot confirm what the flow and return pipe sizes are. My suggestion was new modern rads and to sell the school rads to pay for the upgrade.

Would you reccomend a surveyor to calculate the rad outputs, i am happy to fit them but dont want the same issue as not fitting man enough rads.

Heat loss the rooms and plus 10% should be fine if you want insurance take the windows as single glazed
