I am planning a rewiring and re plastering of a house so I have the opportunity to rethink and plan whole wiring circuits with future home automation possibilities (not much time to design and install a home automation system right now). So I have few options: The domestic traditional wiring system for a house which separate circuit for each area connected to the consumer unit. In this option there are several sockets or lights in one circuit. There is an alternative more expensive to install, commercial model wiring system which circuits run almost for each sockets or lights individually from a distribution board, so you have a centralised control panel of the all power outlets and lights as well. This options seems complex but more manageable if you are planning a hard wired home automation systems which I am considering not now but as a future upgrade. What would you suggest for rewiring when considering hard wired home-automation-ready option as well, if I would like to go for a distribution style wiring system by running cables most of the lights, switches and sockets individually (and some extra network, sensor cables as well) then make all necessary connections in the distribution panel ?

is it cost, comfort or health related? It seems the IR panels are usually "far infrared" : https://www.renewableenergyhub.co.uk/main/infrared-heating-information/types-of-infrared-heating/

Thanks . This is where I got confused. The following old blog claims IR heating is more efficient and cheaper then convection heaters to heat up a typical room but hard to find a "personal experience review" from an infrared heater user. https://www.thegreenage.co.uk/the-running-costs-of-infrared-heating/

Hi; Looking for electrical alternatives to heat up a small studio As the walls occupied with furniture its hard to find a space to hang an electric radiator. I came across this "new infrared panel heating" alternative which is quite space saving and claims energy efficient as well. https://www.victorianplumbing.co.uk/hudson-reed-600-watt-infrared-heating-panel-h1800-x-w300mm-black-glass-inf006?campaign=googlebase&gclid=EAIaIQobChMInpnY-83h5QIVkEDTCh3YcgcZEAYYASABEgJ3EfD_BwE&gclsrc=aw.ds https://www.theheatingboutique.co.uk/standard-infrared-white-infrared-heaters-h600mm-x-w900mm-600w-thermostatic.html?gclid=EAIaIQobChMInpnY-83h5QIVkEDTCh3YcgcZEAYYByABEgIA4fD_BwE Whats your experience on infrared heating panels ? how efficient and reliable are they? Is it comfortable enough to heat up a 20 sqm room?

I guess you are accredited but in Wales I need one in SE London. Also I need some advice about "manifold for pluming for water and central heating radiators as well as UFH.

is fitting requires any special design or considerations? should it be fitted only by the sunamp engineer? any idea about the supply only and with installation price of the models?

Will be rewired with a separate supply & meter

I will check that (sunamp) heaters. the uniq6 is 3.5 kw only and claims replace the 70l water tank, I just wonder if they can supply enough hot water for a shower (or at what temp and rate in winter) I think this is the website: https://www.sunamp.com/ But I could'nt find any online price or seller yet.

Not very well insulated as it was an old bungolow, so no wall insulations but windows, floor and roof is ok. Quite small actually, its about 20 sqm. Probably the easy and less expensive way is one undersink (unvented), one electric shower (9-10 kw). and a couple of electric radiators. (https://www.electricradiatorsdirect.co.uk/haverland-smart-wave-electric-radiators-anthracite/) There is an multiport 11kw Storm Instant hotwater heater which can supply for sink and the shower hot water but not sure if this is any better or reliable option then the first one. https://www.toolstation.com/strom-11kw-touch-instantaneous-water-heater/p78066?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&gclid=EAIaIQobChMIjeKD2bvd5QIVh63tCh1nhA60EAQYASABEgKZZPD_BwE

maybe this could be an other topic but I have no idea about heat pumps. Are the air source heat pumps powerful enough to use as the main heating source of a house (DHW and heating) or are they good as a secondary source to support main the gas/electric heating system of the house? (say for a 3 bed detached house in London/UK)

yes I am considering UFH for the kitchen and entrance hall but not sure how effective they are for the bedrooms as there is not much floor space after the furniture and bed. Actually I was considering to use one of these between joist UFH spreader plate systems but again have to see if they are good enough as there will be no screed on top for thermal storage, just the hot pipes, spreader plates and on the top, floor finish. (i think better to use tiles instead of hardwood as finish) My previous related topic and link for UFH: https://www.theunderfloorheatingstore.com/confused/water-underfloor-heating-for-between-joists-or-suspended-floors

Hi; For a converted small studio, I can't put any gas combi because of the lack of space and gas supply. Is the electric combi boilers like STORM (https://www.screwfix.com/p/strom-sbsp15c-single-phase-electric-combi-boiler/655hr) good alternative? or is it better to have separate electric shower and electric radiators and a small unvented water heater for kitchen? or is this multiport system good enough to supply hot water and shower? ( https://www.toolstation.com/strom-11kw-touch-instantaneous-water-heater/p78066?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&gclid=EAIaIQobChMI2oTorr3a5QIV0-R3Ch3o1wvUEAkYBCABEgIfG_D_BwE ) How are the alternative solutions compared by running cost, reliability wise. So which electric boilers/heaters would you suggest for hot water, shower and heating for a small studio? Thanks

2 large rooms in a family house converted to studio/ensuite rooms. We would like to separate the utilities for these studios so can we get 2 more meters with separate accounts from the utility company DNO? or if multi accounts not possible in the same address then can we get 3-phase electricity with 3 separate meters so that we can use two phases for studios and one for the main house? Is there any differences between operators or availability in the area? Thanks.

Yes you can ! Loxone have a comprehensive knowledge base so if you are tech savvy you can do it yourself. According to their website, in general 50% of the cost is labour, and 40% wiring and equipment. If its just lighting, heating stuff you would like to automate, it shouldn't be that high but if there are some high tech multimedia, home cinema gadgets then it add ups quickly. If you have the detailed quote have a look and see what the breakdown of the 30K quote. There was a ebay sellers, offering loxone design, installation and programming. Maybe worth to talk a couple of experienced technicians and even direct to loxone to see how you can split the work and the cost.

Thanks, thats what I would like to do. I am considering to add actuators for each of the zone/room to have a roam-based control.

Hi All; We need to insulate the timber joist floor rooms which have curved bay window radiators as part of renovation. While looking for insulation boards, I came across these between joist UFH solutions: https://www.theunderfloorheatingsto...eating-for-between-joists-or-suspended-floors I would like to get your advice and opinions on: - the "spreader plate" and "foil board" solutions seems easier to install but I wonder how efficient they are as there is no "thermal storage" screed. - around 50% of the bedroom floor area is covered with king size bed and furniture so the open floor area is limited. Is this enough for the UFH efficiency? - shall I keep the bay window radiator as a back up on a separate zone? - I was told there are manifolds for central heating with radiator systems as well which makes zone control quite easy and efficient. Is it worth to change pipe works of the other rooms' radiators as well with centralised manifolds? Thanks for your helps
