Is the Dexpro Delux water heater tank glass lined?

The dexpro water tank is made of steel and lined with Blue Diamond Enamel. This enamel is rust proof, a quality water tank designed to last. We offer a minimum of 2 years warranty on the tank! 

Is this water heater easy to install?

Yes, the Dexpro is supplied with steel wall mounting bracket and fixings. Pre-wired and requires a 13A power supply. See download tab for the manual and installation diagram!

How long is the power cable?

The power cable is 850mm and situated top left rear!

What accessories are supplied with the Dexpro?

The Dexpro Delux is supplied with: User Manual, Wall fixing kit, 2 x Dielectric junctions and 1 x Pressure Relief Valve to be installed on the cold water supply line and discharged to drain via tundish! 

Do I need any accessories for installation?

Unvented water heaters can be plumbed straight into the cold water supply; and hot water supply directly to standard taps or mixer taps. However we would always recommend that this water heater is installed with the 2ltr Expansion Vessel. The expansion vessel may be required if the cold supply pipe is not long enough to allow for the expansion of water when it is heated inside the tank. Your plumber will be able to advise you best if the expansion vessel is required!

Do I need to use an expansion kit with the 15ltr Dexpro Delux?

For the 10ltr you don't need to use an expansion vessel if you have a minimum of 4.2m of 15mm copper pipe on the cold water side, this means there are no other draw off points in between the 4.2m copper pipe, this will allow the water to expand and contract naturally as its heated inside the tank!

Can this water heater be plugged in?

In the UK all Electric water heaters require a 240-volt dedicated circuit, which serves only the water heater and no other appliances or devices, this is a UK standard for the safe installation of electrical wiring and equipment!

What power supply do I need?

The current intensity of the 6, 10 and 15ltr is 13A!

How many sinks will the 15ltr serve?

The Dexpro Delux has a Whirl-flow inlet this is designed to give 20% more heat output, therefore the 15ltr is suitable for 3-4 handwash basin or small sink! 

Is this suitable for a shower?

15ltrs would be enough for 1 x quick shower, lasting no more than "2minutes" before the hot water starts to runs cold. Also the cold water pressure to the tank would need to sufficient. Instant electric water heaters are more energy efficient for showering environments!
