UNDERSINK WATER HEATER INSTALL - Kingspan Undersink Heater

How to install a point of use water heater under a sink. If you need hot water in a kitchenette and can't get a hot water supply from the tank, a point of use (or undersink) water heater is a great way to solve the problem. I show you how to install the water, what considerations you should have with the electrical supply, water supply and pressure relief valve discharge, finishing with a lovely song about what we've learnt.

Really great detailed video as ever. I fitted a similar one recently and reused the original pressure reducer, pressure vessel and pressure relief valve as they were originally fitted. The hot water deliver with the new heater was really fierce when the hot tap was first turned on and then after about ten seconds ended up as a trickle. A friend who used to be a heating engineer told me to replaced the pressure reducing valve. I took his advice as i’m a qualified plumber with Part P but not hearing quals yet. This solved the pressure surge but now the valve gauge gets up to over 3.5 bars when the taps are off and the relief valve is releasing a trickle of water continuously. My assumption is that the pressure vessel isn’t doing its job and although the relief valve is rated to 6bars it has a relief setting of around 3 bars. Also the original vessel was plumbed in right next to the relief valve and is level with the feed at the top of the heater and is located in line between the regulator valve and the relief valve. You mention a 30mm drop to the pressure vessel. I don’t recall seeing that in the installation instructions and the customer has mislaid them. Do you think my diagnosis that the pressure vessel is faulty could be correct and is the 30mm drop crucial? Thanks and keep up this great channel please. Will find you and post a message on Insta too as you’re an Instagram fan.

I've got to say James your editing and video skills have come on leaps and bounds over the past 3 years.

Going the effort to create your own vocals with humour is leaps and bounds above what other plumbing related channels worldwide efforts.

You are an example for putting effort into your channel.

Absolutely solid filming, editing and content ideas here.

Thumbs up, oh and also THOSE FULL BORE LEVER HANDLE VALVES LOVESSSS

Nice video, shouldnt the expansion vessel be installed vertically to prevent stagnation? 👍

[DanteSinfernoftwww]

Hi there, great video! I was wondering if you could tell me how to fix a leak on one of these?

[samebloke]

Valuable video. Can you please tell us how one of these would work in a mobile setup? We are setting up a coffee trailer and for compliance we intend to run a flojet pump to an under sink heater. Using a Y junction, we want to run a line via the heater and up to a flick mixer hot side and the other line up to the cold side of flick mixer. Is this viable with an under sink heater?

Shinyyyy copper ^_^
I like the look of one of these; they'd be very handy when the boiler packs in in the winter and you get sick of boiling kettles :P
