gravity fed system

Hello, I live in a two floor semi with a gravity fed conventional gas fired boiler (Potterton Kingfisher MF). The boiler is fed cold water from the loft water reservoir tank (which also feeds the cold water taps in the bathroom). There is an expansion vessel attached to this cold water feed to...

A question if I may before I dive in. I have an old gravity fed CH system which thanks to members here in the past - works very well. It has a Danfoss Randal 3060 programmer that has died. I have the original installation docs for the programmer - and it shows 7 terminals plus the earth. In the...

I am looking at replacing my current mixer shower with a power shower (no pressure water just drips out). The system is gravity fed. Cold water straight from tank in loft space, hot water comes out of tank in airing cupboard in bedroom at same level as bathroom and goes into loft space (up...

I have just changed my very old mixer for a Triton Pirlo thermostatic bar mixer shower (from Screwfix) but the flow/pressure is now barely acceptable. I've tried different shower heads including ones designed for low pressure systems with little improvement. The shower and hot water cylinder are...

have an old system, large water tank and small f&e tank on loft, hot water cylinder on first floor, boilder on ground floor (Ideal Mexico Super C 125, vintage 1987, works well though had new stat put in recently). Would really like to just change HWC and leave everything else in place, though...

Hey all o/ Here's the situation: In our rented home, we have an old Potterton MF RS 70 that has gravity hot water, and pumped central heating. It does not have any zone valves, but has a programmer that allows the CH to operate from a room stat when the HW is on. The trouble with this, is...

tl;dr: Why install RF36 instead of HRE36 or Ideal Logic+ 35? How does weather comp/new thermostat differ to boiler's internal modulation? Is a non-pumped gravity shower acceptable (better than an 8kw electric) upstairs even with very old slow recovery HWC, or just go combi at 13lpm in small...

So when i run the tap the cold is powerful but the hot isn't. The tank for hot is in airing cupboard, what mixer shower preferably about £100 should i be looking at as i guess it will equal around 0.1 Bar pressure. Can anyone give me any suggestions. One thing i'm confused on Mira showers say...

Hi all, My brother has moved in to a new house which has a gravity fed central heating and hot water system. There is a hot water cylinder in first floor airing cupboard and hot water and central heating header tanks in the loft. His current shower is a standard mixer valve (non-thermostatic...

So we've just had 2 quotes for new boiler installations, the price isn't the issue as such but the opinions between both engineers who are locally run, and have been around for 20+ years. Our house is a 3 bed detached and about 890 sqft, so not a huge house really, 4 radiators downstairs 4...

Hi, I'm trying to get my head around what's required to install a semi pumped system with a Rayburn Royal. I'm likely going to fit a high output boiler into it for a start, in case someone pipes up with "forget it" :rolleyes: I've got a garage full of logs and some, plus a Rayburn in there...

Hey guys wondering if anyone would be able to clear something up It's been bugging me as I can't figure it out. Read a bunch of stuff but still no luck. So basically I'm trying to figure out how our heating system in our flat works. We have a water tank boxed in above bath area. From previous...
