    Expansion Vessel Size.

    To clarify, I have no training. My question was intended as a question, not as advice.

    Replacing plastic outside light with Metal type

    One order of magnitude at best.

    Expansion Vessel Size.

    Just out of curiosity: if it's got a safety valve, how is it going to explode? What extra does a qualified un-vented plumber have to learn that a non-qualified one wouldn't know?

    Compression fitting size for mains inlet (photos attached)

    I had something very similar in my last house. Black plastic pipe of a bit less than 22 mm diameter. I wanted to change from 15 to 22 mm stopcock. I found that the existing nut and olive on the plastic pipe was a perfect fit on the new stopcock, so no messing around with inserts or new...

    WiFi connected TRV heads

    The point of a connected TRV is to keep the boiler on when there is a room where the radiator needs heat. In the conventional set-up, you heat the hall with the rad on full blast until the hall is nice and toasty, but if your lounge has higher heat loss, or a smaller radiator then the system...

    Whistling TRVs

    I have a sealed central heating system with TRVs on all but one radiator. Radiators are on 10mm plumbing. When the room temp is getting close to the TRV setting, the radiators make a really high-pitched whistle, sometimes for many minutes before the TRV shuts off the radiator. It's definitely...

    Cable management in an airing cupboard

    Is this considered acceptable, or should the flexes be under a cable clamp? It's in the airing cupboard, so the devices they're attached to don't move, and there would be no reason to touch them - except by accident. (Posting here and in the UK electrics group to see if electricians and heating...

    Smart meter... To install or not to install?

    I've had the smart meters from OVO for about 7 weeks now. I used to take a reading every month and put the numbers in my spreadsheet. Now I can read them off the OVO website, and they do all the fancy comparisons with last month etc. and tell me how much I'm using daily. I haven't worked out...

    Micro CHP

    I'm expecting to have to replace my central heating boiler very soon. It's a big house with 20 odd radiators and UV hot water. There's been a lot of talk recently about smart electricity grid, electric cars and feed-in tariffs etc. I was wondering about a gas-fired micro-CHP unit to generate...

    Megaflo bubble recharging or expansion vessel

    I have a Megaflo cylinder that is about 18 years old. How often should the bubble need recharging? It drips into the tundish when it's heating about every 2 months, and recharging the bubble solves this. (I always leave the valve open until the downstairs taps run completely dry.) Does this...

    Weather Compensation

    I don’t want to discuss the arguments for and against Weather Compensation – it’s been done on other threads. So for this thread, can I ask you to make the assumption that WC is a given – I’m planning to buy a gas boiler that includes it. Could I ask those of you with experience of installing...

    Thanks for the advice Dan and Richard. Any particular reason you recommend the Intergas, Dan?

    Replacing vented boiler on a sealed system

    My central heating is sealed radiator system with an external pressure vessel and pump, megaflo hot water, heated by a Potterton Suprima boiler. The boiler's getting old and I'm expecting to have to replace it shortly. All the advice seems to be that a sealed system should have a system...

    Well Fitted Boiler?

    But can you be specific? My recently installed Vailant 937 looks all neat and tidy, but how do I know if it's a good job?
