Heat-pump hot-water cylinders

Dimplex, heat pump, DHW, renewable energy

Dimplex’s EC-Eau range of heat-pump hot-water cylinders offer mains-pressure hot water with low running costs, reliable hot water and ‘fantastic’ flow rates for a wide range of domestic and light-commercial installations. These heat-pump cylinders offer the same efficiencies as the rest of the EC-Eau range.

They are available with capacities from 125 to 300 l and specifically sized to match the requirements of Dimplex heat pumps for optimal performance — although the cylinders are suitable for use with a wide range of heat pumps.

For applications where space is limited, the range includes heat-pump cylinders with integrated buffer tanks. They are available with capacities from 125 to 210 l, all with a buffer capacity of 75 l.

A corrugated heat exchanger has a large surface area to maximise the transfer of heat from renewable energy to the stored water.

To minimise heat loss, these cylinders are insulated with 60 mm of foam injected insulation that is free of voids — including the insulation around immersion heaters and thermostats — and exceeds CHESS ’best practice’ standards for standing heat losses.

Recessed immersions and thermostats reduce energy wastage. Hot water is drawn off from the side, rather than the top, to minimise heat losses from the top of the cylinder.

All models include an immersion heater for high-temperature sterilising and back-up heating.

Grenfell is the building industry's Piper Alpha says CIBSE

The recent passage of the Building Safety Act is a welcome recognition of the fact that making safe buildings is a highly skilled operation says the Chartered Institution of Building Services Engineers, endorsing the need for more effective regulation and a profound change in culture.

Underlying project-starts uptick indicates gradual recovery, Glenigan data suggests

  • 13% rise in detailed planning approvals against the preceding three months
  • 18% decline in main contract awards against the previous year
  • 9% increase in underlying starts during the three months to May

Glenigan has released the June 2022 edition of its Construction Review.
