thermal store

Dear Plumbing Community-I had my boiler replaced with a Thermal Store cylinder over two years ago and had the first servicing last week. It has prompted me to question whether it's working as it should and as cost effective as it can be, because I've noticed since my plumber serviced it, it...

Old Ferroli combi boiler (with the combi function no longer used, I believe copper HE), directly charging an approx 170l thermal store. Does everything I want from it - or will when I find time to get all the controls as I want them (individually controlled rads, variable flow temp depending on...

Hi, Somebody please help! I have recently moved into a home with a Telford Tristor Thermalstore used to heat the water in the flat. Problem is that after 1 and a half showers, hot water has run out. In fact, the hot water is never really that hot. A plumber has been over and changed the...

Is there any reason why I couldn't convert a non vented thermal store to a vented version by replacing the AAV on the top of the cylinder with a header tank? I don't trust the aged back boiler to be pressured on my new second hand log burner and also don't want a pressured vessel

I have just installed a hot water thermal store and have pressure of 2 bars after the titular valve. When I adjust the blue tap (on left of image) clockwise or anti-clockwise, it makes no difference to the pressure. Do I have to do anything with the Allen key adjusted small black ring on right...

Hi all, First post and new territory for me . The rad and valves in my sons 1st floor room needs to be swapped out due to a leak from the (old imperial sized) rad itself. I managed to get as far as rad removal, but the water pressure coming from the feed side is constant and significant. After...

Hi, I appear to have an issue with my Intergas boiler connected to my thermal store. It is recommended to keep the thermal store (Gledhill TGH350) at 75c. I have the boiler set at 85c, but after taking the boiler flow temp earlier (before CH came on) at the boiler and at the thermal store, it...

Thermal store is now in, woodburner heating it via a loading valve (direct). Anyone using a woodburner to heat water, loading valve is a splendid thing- stove heats up much more quickly and seems to burn more evenly and use less fuel to achieve the required effect, all good. But back to the...

Finally going to connect the thermal store to the woodburner. Height differences are a bit marginal- about a metre vertical on the hot across 2 metres horizontal. I'll be using a pumped loading valve so under normal circs this won't be a problem but under abnormal circs which works best- a...

So the plan is this. Currently I have all rooms individually controllable through programmable TRVs allowing me to heat only the rooms that are being used on different profiles during the day and night. So far so good. But I have three main problems with my boiler. 1. there is no boiler...

Hi - I need to replace an old vented thermal store because the eco7 immersion has gone and the plumber has advised that it's seized in place and the whole tank will need to be replaced. The tank in question is a Gledhill Torrent (which I don't think are made now) but I've looked around and it...

Another chapter in the House of Pain. Apparently I can't put my proposed 700 litre thermal store where I want to put it (ground floor to the right of the woodburner) cos there isn't enough rise for the thermionic syphon to behave properly. The thing will weigh about 850kg when full and is 600mm...

hi, I’ve got a thermal store water heater running on two immersion heaters, one boost and one on eco7 circuit. The eco7 one seems to have started working only intermittently. Occasionally I’ll get up and find that the water is running cool when it should have been heated overnight. Usually it’s...

OK, I last posted in here in 2009 with guidance given on a new system. https://www.diynot.com/diy/threads/thermal-store-heat-bank-or-two-combis.170502/ At the time I was running 2 combi's twinned to supply whole house. In the 2009 post I was looking for guidance into a replacement system as...

The House of Pain Heating System will have (eventually) big woodburner, maybe thermal solar panels and probably a gas boiler all driving a thermal store (700 litres is what I've been told I need) with an immersion heater in it for emergencies. Output (radiators) will run from the thermal store...

Hi everyone, My partner and I live on a tidal part of the Thames on a little wooden boat. We're in the process of building out new dream home - a steel Dutch barge, and we're looking into the best ways to heat it. At the moment we're strongly considering a pellet stove boiler, linked up to...

Hi, I'm fairly new to the renewables field but having recently moved into an older property on an exposed coastal site, I've started looking into various possibilities for improving both efficiency and energy storage. The house is a detached upside down style with a stepped footing on a sloping...

hi guys, my current boiler (potterton suprima 80L 2003/4 installation) is causing me grief and a gas engineer has suggested replacing it.. The problem is the hot water fluctuates (heating is fine) i also have a Gledhill systemate 2000 but apparently that is working all fine… Whilst i will try...

Hi All, I've been studying this and other forums for months off and on and putting all the ideas into a do it all system. I am posting my plans for fitting a heat bank to a combi boiler using a converted 300L unvented cylinder for comments / suggestions and probably ridicule. First a bit of...

I've recently converted my cylinder into a basic thermal store, and would like to know whether I need to protect the plate against limescale please? The water here is hard, and the store temperature is 65 degrees. I have a hunch that limescale shouldn't be a problem, but would like to ask the...
