fitting out a new en-suite room in loft

[magico]

hi all,advice needed please.......i`ve installed the toilet and sink and electric shower,all connected to the mains water.all overflows installed............but how the hell am i gonna get hot water up there?
i have a back boiler behind chimney in dining room,a thermostat and timer........i don`t have hot water unless boiler has been on for atleast 1/2 hour. my copper tank is in cupboard in bathroom with plastic tank over top of that and another in loft(with dirty water in)......since i had to move the tank in the loft to the right abit the pressure has dropped in main bathroom and downstairs sink?????????how do i solve this problem too please

Left it a bit late to be thinking about this only now !
I guess this is just for the hand basin as the shower is electric, so why not go the same way there and get an instantaneous water heater something like this;

although there are smaller and cheaper ones around too.

if it is only for washing your hands

whys it late to be thinking of this now? as for the undersink suggestion errr...not really m8. can`t i install a pump of some kind?you want pics or summat to give you more ideas?

 

[bathjobby]

Well, if you can't see why its a bit late thinking of the fundamental service supplies after you have built the room and fitted it out I'll leave you to it.

 

[kevplumb]

the only way you will get the hot water up there is to raise the tank higher

trust me..all considered stick to putting in an under sink heater of some kind...it does not have to be under the sink ...hide it somewhere else and simply run a pipe to the hot tap..they run on mains pressure.
....its enough to fill the bowl..shave..wash hands etc

My take on this (use the average of everyone's!)
You could pump water up there, but they're noisy and they leak and it would be on the floor below - poor option.
You could use an over-counter electric heater like kev showed. Cheap. My neighbour has taken this option and regrets it. They just don't work all that well.
You could use an under-sink heater, up to 15 litres, 2 or 3 kW, around £100. You need to get a pressure relief pipe through a wall, and there are other plumbing requirements that diy'ers usually leave out (and many live to regret that). You choose the temperature, and they work well. Definitely the best option in my view.

One of THESE might do the trick

Similar to that recommended by bathjobby but you may find this better

Heres just some of the bumff

Features:
Water supplied to one or two outlets
Water outlet via existing tap or mixer (especially suitable via spray tap)
Plumbs directly into cold water mains
Flexible mounting
Small compact shape
Remote fitting option
No standing heat losses
Fast response
Two heat settings
Neon 'power on' indicator
12kW unit is the highest rated single phase heater on the UK market.

I wonder why the original poster is so negative to the obvious and pretty cheap solution of an undersink heater?

There is a much more elegant solution! He could fit a thermal store heated up by the back boiler.

In reality he would be able to use a standard HW cylinder as the thermal store and then he could have mains pressure hot water in the basin virtually all day long as long as the flow was not more than about 5 litres per minute assuming a 15 kW back boiler and no other calls for heat.

Thats a good sugestion Agile.

Remember a 12Kw water heater is gonna need a long length of fat copper wire running up from the consumer unit off a dedicated mcb (fuse).

with big socialist brother's Part P that ain't gona be a DIY job. If it were my basin, I'd go with Kev's kettle and get up earlier.

 

[Agile]

If its a kitchen or bathroom, he says a toilet, sink and shower but probably means a basin rather than a sink, then surely he should feed it from an RCCD instead of an MCB ???

[kevplumb]

both i would have thought

 

[brumylad]

Neither,........ he would not have the appropriate NIC certificate for his selling pack or whatever and his house would be worthless.......Right

He needs to get a qualified person who knows how to drill holes, cut and strip wire properly. As for the RCCD, like Kev says most CU's have them built in (although the rating would have to be checked, something like 45 amps). If this is the type of cu magico has then the wire is connected to a MBC.

sorry been busy........i like the look of that one bathjobby........what else would i need apart from the unit? how do i connect it? does it need to go directly to lecky box?
