REPLACEMENT BOILER ?

D

DAJ

I have redesigned my bathroom. 2 basins, 2 person spa bath with hand held shower, a walk-in shower with 4 body jets.

2 heated towel rails (one electric ,one central heated) 9" TV in the shower, 15" TV above the bath (both waterproof obviously) and mood lighting.

I carried out all the plumbing myself and no leaks! Looks fantastic, BUT the bath tap cannot be opened too much, so the bath fills very slowly, that's if you want it hot, and the shower varies in temperature whilst using it.

Basins are fine. The boiler is just a 27k Jaguar (Glow Worm ). I am aware that the heat exchanger needs replacing (F codes, boiler cutting off and on) and I have one ready for a plumber to install .

Can anyone tell me if it is worth doing or is it time to stop trying to make a mini do the job of a van! If so, can anyone recommend a boiler that will do what I want it to (provide hot water with a good flow) and when I want it (straight away).

with all the time and money you've spent on the bathroom its hard to know what your hot water requirements are in terms of flow. I'd suggest you buy/borrow a flow cup or get familiar with how to test flow rate. Work out the kind of flow rate you would like to achieve. Your current boiler will give you around 11 l/min with a 30c rise in temp. If this is not sufficient then replacing the boiler is the only remedy.

No offense, but I think a 27 kw jaguar is very minimalist for a super duper bathroom.

The 9 inch telle is worth more than the jaguar.
You have missed the absolute basic after spending a lot of time and money on your design and that is is the appliance good enough to supply my needs.
Change it for a 37 or 42 kw combi if your wanting your body jets to work as they are meant to . That is after making sure you actually have enough cold mains pressure

Do it properly. A high flow combi is what you NEED. Look at the ATAG 51kW or the W-Bosch 550 Highflow. Ethos do a 54Kw Combi as well.

Check the main water pressure and flowrate in litres/min.

4 jet body shower. nice. hope you are not on a water meter!

Yes he will need a massive, very expensive cylinder as well. Instantly heated water is the way.....

er, if you read what the OP has installed you may agree that cost is not an issue. massive? size is relative. a decent combi over 35kW is going to set you back a lot more than an unvented cylinder. the unvented cylinder also provides an upgrade path to solar thermal.

instantly heated water is not always the way. if OP desires such a system then a Rinnai Infinity would get my vote.

An unvented cylinder and boiler is far more expensive than one high flow combi. Look at the links I gave and figure out DHW delivery. The high flow combi wins hands down.

Good multi-points - I love em. Super reliable. However they do not import the higher flowrate condensing versions to the UK yet, and to get 25 litres/min, you need to have a meter upgrade when using a CH boiler as well - it exceed a U6 meter.

The ATAG, Ethos and W-Bosch 550 Highflow will give 25/26 litres/min. The first two will give 25 litres/min for ever and deliver 1,500 litres DHW an hour. Look at that again...1,500 litres and hour. To get that using a cylinder you will a super expensive commercial sized cylinder. You can have a large body jet shower and no problem of running out of DHW using an ATAG or Ethos, as you will using a cylinder.

Do the sums. Then look at the prices to get the same DHW delivery.

OP, you may want to take george's drivel with a pinch of salt, much as he would like to be a RGI, he is not, and has never legally installed a boiler. He is actually a troll that has been repeatedly banned for posting wrong advice and abuse.

Sorry mate - not sure how/why the amount of time and money spent would make it hard to determine my needs! The question is, at this stage, new boiler? if yes, which one/type. Cheers anyway.
