Domestic Water Heating for a Village Hall

AncientMariner

With the summer being the quiet time in our village hall, it gives the opportunity to arrange for works to be carried out.

Currently, hot water for the kitchen's two sinks is from a 10/15 litre under sink water heater which struggles to give sufficient hot water for those sinks and takes 20/30 minutes to recover. A separate bar, has an over sink water heater, again of insufficient capacity.

What I am thinking of is an instantaneous water heater. There is a three-phase supply within 6 metres of a suitable location for an instantaneous water heater, this would have an advantage of only consuming energy when water is flowing, whereas a storage system would have energy wastage.

At home, our combi boiler (a Worcester Bosch Highflow 440CDI can supply 20 litres per minute and I can see that it is rated at 29.5 kW.

Google has found me a Stiebel Eltron DHB-E 27 and their similar models between 18 and 27 kW.

Has anyone any experience of Stiebel Elton's products or any other similar water heaters?

Many thanks.

    Thanks Mike, Kevin and Andy

    Nothing adverse, so will get a quote or two for fitting etc.

    Luckily the water is fairly soft and the supply pipe is 25mm MDPE fitted two years ago back to the water main when we got rid of the lead pipe.

    I will not be doing the work, but for checking the quote,  5-core 6mm² SWA would seem to be an overkill, would H07RN-F again 5-core 6mm² be satisfactory? The cable would be running within an existing cable duct.

    Thanks.
