Hi, Apologies for the reposted question. In simple terms I need to run pipework to new radiators on a ground floor flat. The existing floors are concrete. I do not want to box in pipes in the corner of each room with up and over pipe runs, therefore :- 1. Can you chase copper drops...

Hi, I wonder if I could ask you some advice regarding two points:- I am converting two flats in to one house and both ground and first floors are concrete construction. As part of the build the plumber (not yet chosen) will be installing a new radiator system and we will also need to relocate...

Hi, just getting some work done on my house. The proposed consumer unit location is under the stairs and around 10m from the meter which is in the garage. The electrician says he will need a switch fuse at the meter end in order to allow the distance between the meter and board is over 2m...

Hi all, Just looking at the Vaillant Ecotec 624 System boiler, it comes with an integral 10 litre expansion vessel. The house is 4 bed 170 sq. metres, all radiators and 10/15/22mm pipework (no underfloor heating) Typically, would you expect the system boiler itself to cope with...

Does anyone know a good 40kW output system boiler, I know Vaillant do a 37 and 45kW version but was after a 40kW model. Worcester do the 40kW CDI but it isn't a system boiler. Any thought's would be welcome. Thanks

We're on with some work at home and would like to run a gas supply to a fireplace but cap it off for now as it's will be a solid fuel fire. This would allow us to make it a gas appliance at some point in the future. The plumber has said it can be done and left at the fireplace but it also...

What would provide more hot water a 500 litre standard coil cylinder, or a 400 litre ACV tank-in-tank cylinder. It is for a large house (linked to my earlier 50kW output boiler post). The property has six separate bathrooms with all the usual draw off demands. I know the ACV would perhaps be...

Anyone able to recommend a good 50kW gas condensing boiler for a large house? Would prefer not to link two smaller boilers. Thanks

Could someone please explain whether installing a buffer/thermal store after the boiler would provide a higher heat output. For instance, if I need 45kW (peak load), would I get away with installing a 25-30kW boiler? Thanks

Hi Guys, What is the main difference between CAT5 and CAT6 cabling. What would you suggest in a small office of ours? Thanks

I have recently moved in a 140sq. metre 2 bed house with a bathroom (containing a bath and a shower) and a separate en-suite (containing a shower). The house currently has no heating and I'm looking for an effective and efficient system. Which combi boiler would you experts suggest!

My friend is organising for new heating pipework in a church (replacing old single pipe cast iron pipework). The plumber is proposing carbon steel pipes, this sound expensive, but it may be the norm? Obviously they don't want to be copper as the majority of pipes will be visible. Also are...

I need to ask (or rather get the plumber) to install a domestic hot water circulation loop across a room (about 20m). The room is yet to be built and will have no roof space to run the circuit in. It must go in the floor. It could go within the floor screed depth, the plumber mentioned...

Hello all, I have a relatively new system installed and there is a very loud over-motorised sound coming out of the boiler room however when one of the boilers gets turn off then back on it seems to dissipate. There are two boilers linked together (2 x Vaillant EcoTec 24's). Does anyone...

What is the correct definition for an emergency light fitting which is an emergency version of a standard fitting, it needs to come on and go off with the rest but also come on or stay on in the event of a fire. Am I correct in saying this is a 'maintained' emergency light ?

What are the rules and regs regarding dropping heating flow and return / hot and cold water services pipework behind stud walls. Firstly, can you do it? and secondly if you can, does there need to be any form of protection of identification foil so the routes can be picked up if someone was...

If a condensing boiler is to be installed in a cellar with no outside wall available I know there are condensate pumps available (by Grundfos or Saniflo etc.) to lift the condensate to above, but my question is, what about the safety discharge pipe from the boiler and cylinder? Can they also...

What capacity indirect hot water cylinder/s would be required to serve 15 showers (i believe the showers consume about 12 litres every minute - hot and cold mixed). There would be 20 people at any one time that could use the showers, i.e. most rooms have a shower en-suite. I just want to...

Hi, is LSF cabling required for Building Regs for a domestic property? Or is standard twin and earth acceptable?

Is there a rule of thumb sizing method for an underground MDPE gas supply pipe after the LP U16 boundary meter, the boundary meter is around 110m away from the building, it will be serving a 50kW boiler only. I am only curious as to what size the builder / RGI will need to price to make , an...
