ericmark - I will go back to the guys that put the system together but i am slightly confused (for the record i am trying to understand how it works, i am not planning on doing this myself). I thought the underfloor heating has its own heating system that takes information from each of the...

I meant to have the boiler running automatically when needed rather than me plugging it in for a few hours to heat it all up. Not free hot water - That would be impressive.

I am looking for some help if i may. The house was re plumbed a few months ago and i am now having the electrics completed. As part of the electrical finals i have asked the electrician to wire the central heating/Hot water system so that i can finally do away with running the boiler for a few...

Are the bases all the same for the Aico models? As in if i install a heat only detector i could swap at a later date for a combined unit? In the garage is it sufficient to just place a stand alone battery CO alarm on top of the boiler? I may go for the combined Aico units in the house to rooms...

Thanks marty. I have a lot of PIR left over/available FOC and my BCO seems to prefer the PIR route even though he excepts both methods are acceptable. Obviously this would be my preference as i have all the materials or certainly most available without buying in more.

I am going to start insulating the floor in my extension and the rest of the ground floor. I will be using 100mm PIR and pan to staple a 10mm thick 100mm deep foam insulation strip to the joist and then cut the PIR 10mm less than the gap between joists so that it will fit in nicely when the...

Is this what I am looking for for the EV charger? https://www.tlc-direct.co.uk/Products/WYWRCBL50B2.html

The EV charger requires a standard size rcbo. I assume that can be installed alo guide the mini rcbo's for the rest of the circuits?

I managed to get the 23 way empty duplex panel. This will be perfect coupled with rcbo's for each circuit.

Is there any reg that staes that spare ways can't be blanked off? If I had 8 ways blanked off would that be an issue? I had always planned on a few to allow for future add ons as and when required (EV chargers etc)

They only have the 29 way units in stock. https://www.falconelectrical.co.uk/wylex-nmd1112-23-way-100a-main-switch-flexible-duplex-unit-1 I assume other than being a bit bigger there is no issue with going with that just need a few more blank plates

I had struggled to find and "empty" unit. The plan was to buy the NMDRS24HI and removed the rcd's and then install rcbos to all circuits. The one you have in the link is basically the empty version I was looking for. On that basis I assume mini and standard rcbos are fine to use Thanks

Why would this be non compliant if sold as part of the wylex current range. I have yet to find a CU with 20+ ways that is not a duplex unit.

Is there any way of telling if this -> NMDRS24HI 24 is a newer or older? I cant seem to find an answer in their literature.

I want to order my CU and RCBO's. I have noticed that there is an option of standard and mini. What do people use? Can either/or be used in this CU Wylex NMDRS24HI 24

Sorry yes i meant CO. Only need them in the rooms with the log burners and the boiler?

The garage has the boiler and main gas supply in it so i guess i need a Co2 alarm in there.

Ok I misread it and thought they recommended replacing every 5 years. A very good warranty in that case. On that basis then whilst the Co2 alarms are expensive they may be an easier option. Not an option if they need replacing every 5 years. Am i correct in thinking the test switch can be...

Thanks for the advice. I have seen a lot of AICO units used at work and always heard good things so maybe that is the right way to go and at that price maybe separate Co2 Monitors. Why are they restricted to 5 years? I always thought the benefit to hard wired systems was that they lasted "for...

Can you recommend the best hard wired, linked smoke/heat/Co2 alarm system. A colleague recommended the nest alarms but they seem to only do smoke/Co2 and i thought that heat units were better for use in kitchens to prevent false alarms. I plan to install the following (is that the correct set...
