We have recently bought a 5 bed detached which has a combi boiler servicing the ensuite, kitchen and the radiators. there is also a vented cylinder which serves the downstairs cloakroom and family bathroom where the pressure is very low. we wanted to move to a unvented cylinder but are getting...

Evening all, I've just bought a Drayton Wiser Kit 1 to replace my EPH Controls (RF1A-OT) and just want to clear something up with the wiring. Here is the current wiring setup: And here are the instructions for the Drayton Wiser Kit 1 (Combi Potterton boiler) Am I missing anything from the...

Hi, we have our heating split across 2 levels - we can control the heating for each floor. On the Horstmann panel in the middle, there are 3 settings - heating upstairs, heating downstairs and water. I leave the heating settings on all the time, but the water is on a timer. My understanding...

Hi, I currently have a combi system and would like to increase the water pressure for all outlets (mainly shower). I have been looking at the stuart turner mainsboost flomate mbf 12 as this states it increases mains pressure by 1.5bar...

I have a Potterton Gold Combi 28 HE on a brand new system following full renovation. However I am unable to get a consistant flow of hot water to any outlet. The temperature holds as hot for around a minute before fluctuating between luke warm and warm. Boiler has previously been sat in dry...

Hi all, I'm getting a persistent leak from my combi boiler unit. It fills a 500ml container a week, so it's not 'critical' just yet. I do not intend to fix this myself. I want to save time and identify what parts I might usefully get for whoever comes and does this repair for me. Here are a...

Hello everyone, I moved in into "new build" back in 2015. Single bed apartment with the following configuration in place: 1) Communal heating where HIU is installed in every flat. Rossweiner heat sonic. 2) KINGSPAN RANGE TRIBUNE HE 210 LITRES UNVENTED VERTICAL PRE-PLUMBED INDIRECT HOT WATER...

Help me please! Moved into this house last year, it hasn't been looked after at all. Gas combi boiler (Alpha InTec 25XE) has always just about worked. It's only ever given us constantly hot water if the tap or shower is turned on to a very low pressure. Even half pressure and it'll run hot for...

Hi all My parents have just moved into a bungalow and the gas combi boiler is in the garage. Any idea why it has an extra stat in there linked to the RF controller and another valve/stat on one of the pipes? I was thinking it’s done form of frost protection/low setting but boilers have this...

Hi folks, Im having problems topping up my boiler. I have read some of the other posts on the forum and thought I found the loop on the boiler but pressure wont shift. Here are the pipes, I am actually in italy. Not sure if that is the issue and pipes are set up different. But definitely cant...

Hey everyone, first time posting here but I am completely at a loss - looked through lots of the other posts and they all cover parts of my problem, but not the whole thing! I bought a Hive dual channel as I incorrectly thought that's what I needed - turns out I only needed a single channel...

HI all. I have got a Worcester greenstar 28i junior combo boiler. The thermostat currently on there is a worcester digistat. This digistat talks to the boiler via RF. I am looking to get the Drayton Wiser thermostat system but want to check it will be compatible with the boiler. To add...

Hello everyone, I am looking to change my naff ESI thermostats to Nest gen 3's and wondered if someone could help me with the wiring. I have two motorised valves in the upstairs airing cupboard along with the wiring centre. I've checked the back of the facia on the wiring centre and there isn't...

we have a combi boiler with a timer that is always on. we then use a wireless thermostat around the house to control when the boiler fires up. if we don't want the heating on, we simply drop the temperature on the thermostat to a point lower than the current room temperature, which ensures the...

Hi, I've got a combi boiler. I was thinking of turning down the temperature of the heating on the boiler (i.e. on the boiler itself not the temperature on the thermostat). Reading up on this it sounds like setting this as low as possible is the best option in terms of reducing gas usage - to try...

It’s not my house but my friend is doing some renovation, she mentioned it to me but she doesn’t know if to get someone out or not to look at it? It’s not owned by her but her landlord doesn’t have time to check and tell her but the she thinks they may be getting too hot and that’s why there’s...

Hi, long story short my hive has been wired using a dual channel receiver on a viessmann combo boiler. Since removing the hub as I’m moving home, it only fires the boiler when I boost the hot water on the thermostat. Spoke to hive who said I should us the single channel receiver for the new...

Hi Can people please offer some advice on the following choice? We are in the process of fixing our old central heating system which is open vented and has almost no hot water pressure upstairs (cylinder and boiler downstairs). Our plumber suggests sealing the system and installing a mega flow...

Hi, Only my 2nd post, but you were all so helpful with the first post I thought I'd have another go. I was talking previously about how I have a fairly new combi boiler (Vaillant Ecotec Plus 832) and also some solar PV and had the notion of fitting a HW cylinder as well. Since then, I've seen...

Hi TL;DR - I want to get a combi boiler to save space but want to increase the pressure of my water by pumping water from my tank through the combi I currently have a 2bar shower pump pumping cold from my tank and hot from my cylinder to my shower. Now we're getting the house renovated, and one...
