Glow-worm Ultrapower sxi

Do you tire of finding no hot water for your morning shower? Do you have a large family which demands hot water continually? The Glowworm Ultrapower sxi is a boiler which is capable of providing endless hot water on demand, even in the largest of properties. This impressive feature is made possible by an innovative hot water storage system with remarkably fast reheat times. All this comes in a single unit which is compact enough to be housed in an airing cupboard. Whenever a hot water tap is turned on within the home, the pioneering shift load storage system allows the Ultrapower sxi to generate hot water instantly. This is backed up by drawing on the internal storage system, and this allows the appliance to rapidly deliver up to 170 Litres of hot water.

The Ultrapower sxi comes in two sizes, 100 liters and 170 litres. The smaller of these two units is recommended for a typical 4 bedroom, detached house, whilst the larger boiler is recommended for a larger home of 5 bedrooms plus. The Ultrapower sxi also boasts impressive environmental credentials; it holds a SEDBUK* A for efficiency, which minimises the boilers impact on the environment and the wallet.

  • SEDBUK A
  • NOx Class 5
  • 5 Second hot water delivery *

  • LPG compatible without conversion kit
  • Back-lit digital display to make the unit more user-friendly

I have lived with this boiler for 3 weeks now. The advantages of mains pressure hot water apply to all such boilers. Of course, with a tank, this boiler can deliver a high flow rate and fill a bath quickly, replenishing the hot water in the tank as it does so. I chose a storage boiler to be able to fill a bath quickly and to avoid having a separate boiler and tank. The boiler is in the airing cupboard and I have liberated space in the kitchen now where the old boiler used to be. So far, there are just two minor criticisms. Firstly, if you have had the boiler off and have only cold water in the internal cylinder and you suddenly want hot water you have to wait a couple of minutes. A more intelligent design would bypass the heating loop of the tank in favour of delivering hot water from the boiler straight to the tap. The second criticism is minor: instead of displaying the target domestic hot water temperature, it would be more useful to display the actual temperature of the tank. This would tell you whether the boiler needs to be switched on to deliver hot water. I will add to this review when I have lived through a winter with the boiler and have had a chance to observe its reliability.
