Hi . I the process of converting a house for HMO. Im a bit concerned about water supply so i am thinking of a gravity system with storage tanks in the roof, as opposed to a mains pressure system. What are peoples thoughts regarding Legionella, and suitability. It will be a completely new system with no deadlegs etc?

Hi Yes standard system would include kitchen drinking water supply. And fortunately there are two supporting walls that form the stairwell that will be able to support a tank stand. Im reckoning about 300 ltrs of water storage..so two 50/70 standard tanks should be ok at 590 and a 300litre hot cylinder...

With regards Legionella, the general rule is that if you don’t need stored water, then don’t store water. Direct mains cold and a mains fed combi-boiler are the ideal
set up in small to regular sized domestic dwellings. It really just depends how many rooms with water facilities and how many occupants there are in the property whether you need cold and/or hot water storage tanks.

A pressurised cylinder would be possible, there could be oodles of hot water and as you are buying from new you could get one that has a coil in it to heat from gas / oil / air source as well as immersion heaters as a back up (these could use off peak or solar panels)
If you have a decent roof then you could have PV saving you a fair bit of electricity.
A combi may not cope with the demand
You may want to get the heating split in to zones (floors) then if the top floor is warm it will shut off, this will also help if it is not fully occupied.

If I was starting from scratch I'd go with baldelectricians advice of megaflow or equivalent. Gravity fed will give you rubbish hot water pressure (which makes it a lottery when buying taps). You'd still need a hot water cylinder, and (unless of course you are going for mains fed electric showers) you would also need to factor in pumps for showers..

by Real_PolitikJust had a mandatory EICR carried out, arranged by the managing agent I should have ditched by now - as expected, it was “Unsatisfactory” and there are numerous C2 issues for which I’m being asked to fork out a big chunk of money. Their approach is that if it doesn’t meet all the 18th edition...

by catdog1121Either this was not rewired in 2010 or whoever did it should be the person you should be questioning rather than the inspector, everything being true in the report (ie there is no RCD protection etc) then the report seems reasonable. You are not being told you need to change the consumer unit just...

Reply to gasby AndrewDodThe question makes little sense to me...
You are saying that the landlord is concerned about something gas related, and wants to check it out, and you refuse? Right? In that case be sure to add to your calm polite letter that you will not have a problem when the house and your contents explode...-

Reply to gasIgnore the accusations. Can't imagine landlord trying to evict over that.
Write/email to landlord, copy agent, keep copy , calm and polite stating terms and times you'd permit a check.
He's probably aggressive trying to compensate for something small and trivial-

Something does not add up
1. You had a 'rewire' in 2010
2. This 'rewire' failed to provide RCD protection for sockets liable to supply equipment outdoors- this bit started to arrive in the wiring regulations in 1992.
3. The IP rating of the consumer unit means the previous contractor...-

by proteuspalHi, I have searched high and low for a specific answer and am struggling to get anywhere. Some answers suggest 10cm, others recommend 30cm minimum clearance horizontally.
I'm renovating a property and where I want to reposition a freestanding 60cm electric cooker, it will be located pretty...-
