Hi,
My flat came without any thermostats on the radiators (looks like a lockshield at each end) and also without a central thermostat for the whole system so I am left with only the timer to control my central heating. This is not really ideal for me and I'd like to ultimately move over a smart radiator thermostat system like the tado one. My central heating is a combi boiler and I am all on one floor.
So, the first step is to fit TRVs to all of my radiators. I've done a bit of research and my plan looks like this:
Step 1 - Drain System
I have found the drain on one of the radiators ... looks like I just attach a hose and follow a step-by-step like this one

Step 2 - Remove radiators one by one and flush them with a hose
Seems like this is worth doing now as I have the system drained and could prevent problems
Step 3 - Fit TRVs and refit radiators
Looking at this one from screwfix. Is it worth getting new lockshields too?

Step 4 - Refill boiler using the tap on the bottom of it to 1bar.
Step 5 - Bleed radiators
Step 6 - Rebalance all the radiators using my multimeter thermocouple and aim for 12 degree difference

Does that sound like a sensible plan and is it viable for an amateur? I can work a spanner and I've fitted a few compression joints etc in my time to give an idea of level of skill. Also what problems should I look out for or am I likely to cause?
Cheers
Phil
