Glow-worm launches small Clearly Heat Pump model

Glow-worm, Clearly heat pump

Glow-worm has added a 5 kW air-to-water heat pump to its Clearly Heat Pumps range. These units have an electric back-up heater and are designed for new-build homes with low energy requirement and can contribute to achieving Level 4 of the Code for Sustainable Homes. They are accredited under the MCS (Micro­generation Certification Scheme) and therefore eligible for possible funding under the proposed Renewable Heat Incentive. These units achieve a COP of 3.79 with an ambient temperature of 7°C and water temperature of 35°C.

They use R410A, but No F gas qualifications are required to install these units. An inrush-current limiter enables a standard 20 A breaker to be used.

The indoor hydraulic module separates the heat-pump circuit from the central-heating system, so there is no need to fill the entire system with glycol antifreeze. The hydraulic module incorporates a 20 l buffer vessel, a 12 l expansion vessel, circulating pump, filling valves for the glycol circuit, PRV and a inline heater adjustable up to 6 kW.

These heat pumps use Glow-worm’s eBus communication protocol so they can be teamed up with a suitable Glow-worm boiler and an alternative hydraulic module to form the Clearly Hybrid system.

More refrigerant bans possible, says government

The government could tighten up the rules that restrict the use of global warming refrigerant gases including speeding up phase-out programmes and introducing new bans, according to a spokesman from the Department for Environment, Food and Rural Affairs (DEFRA).

Baxi research suggests schools strongly support heat decarbonisation

A survey conducted by Baxi of 200 state school estates managers, consultant engineers and M&E contractors has found that while enthusiasm for Net Zero and support for low carbon heating systems in schools is thriving, persistent barriers remain.
