Should I worry about pipes freezing in conservatory??

[scooby_snacks]

Hi guys, in the process of completing my conservatory, plastering dwarf walls, flooring etc and now come to hanging the radiators.

I intend to run the central heating pipes beneath the laminate in a cavity in the suspended concrete slab. The 15mm pipeswill be lagged within the cavity. I intend to put TRVs on both rads and encorporate isolation valves on the inside of the living room so I can isolate this run completely. I could look at zone valves etc etc but I'm doing this on a budget.!!!

What concerns me is the possibility of the pipes freezing come winter. Do most people leave rads on to prevent freezing, but waste money and gas in the process? Do people routinely isolate and drain down? Stupid question perhaps, but having just built my own conservatory I'm only too aware of what my potential heat losses will be. Should I at this stage be looking to encorporate a drain off cock right at the lowest point to get every drop of water out. Am I just clutching the purse strings too tightly?? Haha

Any feedback greatly appreciated, Cheers

If you can I would definitely incorporate a DOC into the system, makes life a lot easier.

You could always fit a frost stat into the conservatory if you are concerned about pipes freezing.Best to interlock this with a pipe stat, but obviously a pipe stat might ruin the aesthetics of your conservatory.

Thanks, not really given much consideration to pipe stats/ frost stats but they could save me a lot of time and hassle. I've got some research to do! Cheers

If you fit isolation valves, make sure they are good quality full-bore lever types. Lesser ones will restrict flow.
