That wall is cinder block then there’s a cavity and outside wall is red brick. I just had the gutters down pipes cleared so presumably not that. The down pipe is the other end of the garage too. I’ve had a look in the cavity with my phone camera and can’t see anything obvious.

I have an external double skinned garage. I have recently turned it into a weightlifting area. I notice an area of the plaster is damp in rain and anything touching the wall is wet. I got a cheap damp monitor device and it is showing 16% in the areas that look damp. I should add the ‘normal’...

I have made my external garage into a gym for weightlifting etc. I am looking to install some insulation boards on the rafters. I have attached pics. They are not deep rafters 10cm which limits what I can do. If I boarded them over with Recticel Instafit Polyurethane 50mm would it make much...

I have thought about this a lot but it’s really just to take the chill out for my small gym out there. Alternative is an electric heater of some description but I figured electric costs more than gas and I’ll have the gas heating blasting anyway when it’s cold? Also have the issue of turning...

It’s a combi so hopefully no major issues. I can’t find out if I need to drain the system? As those pipes are dead legs I don’t think they have water in them so presumably wouldn’t need to drain?

I have a few radiators that the installer fitted the TRV on the flow and the only issue I’ve had is I find them harder to balance but that may just be me.

Is there a way to tell which is flow and which is return? I had assumed the drain off one would be flow?

Thanks. I think they are. There was some talk of the installer putting a radiator in but it never materialised.

I have recently had my old non condensing oil boiler in external garage changed to a gas combi elsewhere in house. I have been left with these pipes which are dead legs and I assume are the flow and return the old oil boiler used. I want to add a radiator to help add some heat to the garage...

It’s copper. I think it might be a gas pipe. I’ve noticed other gas lines in the house for gas fires from a tank that look very similar to it. But I can’t work out why that would be ran to the garage and left like that with an oil boiler beside it as well

I don’t think so but I’ll check again. I also pulled out a pipe that I assumed was the oil line. Much thinner and went to oil tank. I’m wondering is it a pipe that’s been left since the house was built in 1996.

Hello Can anyone help me identify what the orange covered copper pipe is in this picture on the right? This is an external garage where an old oil boiler has been removed for a gas combi elsewhere in the property. This pipe has always been there. Simply nailed to the wall. I had always assumed...

Thanks I’ve no zone valves but I suspect getting an acceptable delta t will be hard. It was originally an oil boiler system with vented tank and quite long flow/return runs 17/18 rads. The house does seem quite hard to heat. It takes a long time for temperatures to rise even when the combi is...

Thanks again. That makes more sense now that I know it connects to the controller on the boiler rather than the sensohome. I’ve seen it as low as 1 but it’s always worked. Can I ask if you have any thoughts on what’s the best pump setting on the boiler for the WC set up. Mine was on constant...

Really appreciate your help. Over here in Belfast installers really know very little about the controls. Vaillant have been reasonably helpful but it takes time to get a response. Does the adaptive curve also adapt up so to speak? Ie if the curve is too low it turns it up. Do you know what...

Thanks for this. I’ve got it set to expanded and adapted activated too. One thing I noticed was on those settings it lets the set back temp go slightly below before the heat comes in. ie I had set back at 18.5 and it didn’t come on when it was 18.4 on the app. It did come on at 18.3. Is this...

Just found this thread as I’ve paired a VR20 sensor with the sensohome controls and internet gateway. I have a 836 eco tec combi. Some great info here. Can I just check when Room Temp mod on the sensohome is on inactive what temperature is it working to? Similarly if I have room temp mod...

Yes will speak to engineer tomorrow.

Alternatively can you run the pipe out the right side but go immediately down and behind the box?

I am in the process of having gas installed. Is there any way to change the outlet side of the brown box to to the left? This may seem trivial but my reasoning for siting the box where It is was to run the pipe out the left side and around the side of the house etc. with it on the right it has...
