I'm looking to fit a radiator in my conservatory, I need need around 7-8 kw @50 degrees to be safe. Looking around, it seems the only ones I can find are Myson K3 at 600 x 2400.

Does anyone know of any other manufacturer of high efficiency rads I can perhaps look at in an attempt to get something a little smaller?
 
7-8 Kw! How big is your conservatory? You are aware that it's nigh on impossible to heat a conservatory to the same temperature as the rest of the house (not to mention in breach of the building regs) in the winter.
 
Why not go with a fan convector they have the added benefit of being able to run the fan in the summer to move the air around a bit.? you can get wall mounted, floor sanding or in-floor /trench type.

You'd be better off in my opinion installing a heat pump inverter driven air con unit. Inverters generally offer 350-400% efficiency, & have the obvious benfit of cooling in summer. People often forget air con heats as well as cools...

I used an online calculator to come up with the heat required. the conservatory is brand new, 6.5m x 3.5 internal, with a shallow pitch roof.

I won't be using it all the time in the winter, only on occasion. Tapping off the ground floor central heating seems the most sensible way to provide heat to me. I understand that it isn't a perfect solution due to temperature control, but it may be the easiest, and cheapest. I cannot stand fan heaters because they're far too noisy! Perhaps the heat pump idea could be a goer, but I imagine the cost is substantial. online calculator to come up with the heat required. the conservatory is 6.5m x 3.5.

True, the initial outlay for a mid sized a/c unit ( not to mention specialist installation ) seems quite steep but over the life of the unit it will more than pay for itself if you go for an inverter, especially if at some point in the future you install solar PVs ( you could run it during daylight hours for FREE!! ). A 7kW unit will give you 7kW of duty for an input of 2kW @ 350%. Don't be tempted to scrimp on the unit as a non inverter model, although cheaper will cost you considerably more to run!
 
What you plan to do is against the build regulations. Just in case you missed it the first time...

Who's gonna stop him? The building is already in place, it's not like building control are gonna come round and tell him to remove it now.

The major issue is gonna be getting an 8kw rad and whether the existing system will support it.
 
best bit is when the rads arent on and then freeze, causing a few problems for getting the rest of the house warm🙂

Thanks, I did see that first time around. I am not exactly quaking in my boots however. and in any case TRV's get around the regs nicely.

Guys, I just needed to know about radiators, that's all. If you want to help, then please suggest some radiator manufacturers who can supply a correct output radiator. Maybe I've got my calcs wrong, and a check for me would be really helpful too. I'm not concerned with any alternatives because the costs and work involved will be too high for me. I intend to fit TRV valves so that I can adjust the heat output, and turn it off when not in use.

I did heat the conservatory yesterday with a 3kw fan heater and a 2kw flat panel electric heater. It took about 2 hours to heat first off, and we turned them down for the last hour we were in there, and it was quite pleasant, but it was noisy with the fan heater. We don't suffer from frost in the conservatory here in the far south, so it's unlikely to freeze my radiator contents.

As stated previously, what you are proposing is against the building regs and there are no ways round them. BUT the likelihood of you actually getting caught and prosecuted is remote. That's your gamble to take.

I would definitely get a frost stat installed though.
 
The heat pump ain't going to be cost effective. Is the conservatory separated by doors from the main house?

install the radiator on a separated zone valve with a time clock and room stat, that will satisfy building regs. Also means you can turn the stat down to 5 degrees in the winter and use it for frost protection.


id be surprised if your heat loss is 8kw, 8000 btu maybe? That's more than my entire house!

The regs exist for a reason and you don't understand why they apply.

If you can't afford to do it properly then why do it at all? Or at least save a little more and get it done right!
