Conventional electromechanical thermostat and 7 say programmer with three periods per day. There's a 3-port motorised valve for HW / CH. Yes, gravity fed HW It would be interesting to know of options. I'm not particularly interested in smart controls, etc. About the only thing i might replace...

Yes, the boiler works fine apart from a bit of kettling. I think a full power flush will be needed as I believe a manifold is blocked and that feeds the two cold rads. I have noted that both of these have no hot flow as the valves are cold, and one rad that is warm has a hot valve on the flow...

MIght be worth a think. I briefly considered a combi, but we had a breakdown a few years ago and were left without heating for about 5 days. The immersion heater at least gave us hot water. Also, getting the HW from the combi boiler to the tank location to connect to the existing would mean...

That was my thinking to be honest. Get to a known good position before changing anything. A full clean should be part of the changeover, and this could uncover other issues but we deal with those if the arise. I think the boiler is OK - it runs and we get heat where the pipes are not blocked...

I have been having problems with cold rads (https://www.diynot.com/diy/threads/number-of-cold-radiators.652613/#post-6150056) so have been getting quotes for a flush as nothing has cured the problem. A couple of plumbers have suggested changing the boiler as the current one is 25 years old and...

@Exedon Any issues with paint flaking on the Kartell rads?

I had three rads fitted at the same time as a new pump and diverter valve by a heating company ( I supplied the rads as I was going to do it myself originally). Only the one in the bathrrom has any bubbling in the panel. I did wonder about inhibitor as they added mine but then had problems with...

I fitted some Henrad raditors a few years ago now but recently noted that two have the paint flaking off at the bottom and one starting to bubble on the face. I thought these were part of Stelrad and better than the average from the likes of Screwfix, etc. Not sure that the 10 year guarantee...

About £2k more expensive so would be a lot of energy to use to get that back. They were the first to quote so and I do not generally say who has quoted Quote from yesterday was about middle of the others, but that was based on having dummy sashes. Doing a bit of a read on the matter suggests...

The profile seemed to be a big selling point of the more expensive quote - more chambers so better insulation. I am having a company quote today and they are fitting the windows for a neighbour opposite so an opportunity to see how they did! I am a little cautious of recommendations as a...

I am looking at replacing our 25 year old original builder grade uPVC windows and french door with something newer as some do not really shut particularly well and the bay window is not plumb in one corner! I have had a couple of quotes - one at around £6k (50% deposit and balance on...

For something without smart switches you could use something like the Steinel Nightmatic 3000 that brings lights on at dusk and can be programmed to switch off during the night from a set time. I thjink it can be set to bring them back on in the morning if it is still dark enough. You could then...

I think that is what I did last time. Job for the weekend

Some years ago I had the same problem and had the hall radiator off and opened one lockshield. That seemed to clear the lack of heat for a while. Might be worth another go

I am guessing at a manifold due to the warmth of the floor in the en-suite although ot could be just the 22mm pipes and joins in that area. I have not put inhibitor in but I did have some that they put in when they changed a few radiators for me. That said they had problems then so they may...

Yes, they worked then I had the plumbers look at it and they seemed to clear a blockage in the hall radiator. I suspect a blockage as the loo radiator used to be much hotter

I have just ried all radiators off except hall, bathroom and loo. The boiler runs for a while and then stops. I assume some sort of overheat? I have lost my bleed key so will have to grab one on my travels, but I did manage to release two of the bleed nipples with a screwdriver. Just get a...

I have a repeated problem with cold radiators. I had a local company to look at the system a couple of years ago which seemed to sort he problem for a while but we are back to cold radiators again. I have a conventional boiler / HW tank system. All piping is plastic and I think that there may...

I need to replace a couple of fans in the house. The first is a ceiling mounted fan in the guest cloaks needs to be one with a run-on timer The scond is in the en-suite fan which is a standard fan and is feeble for the duct length of about 4m I have looked at the Manrose CSF 100T and CQF 100T...

Were to 100 / 200 those used by Wickes way back in the late 80s or very early 90s? I have never seen one of these sounders in use
