Solar panels are part of heat-pump DHW system

Ultima Solar, renewable energy, heat pump, domestic hot waer DHW

Ultima Solar has been given the sole distribution rights in the UK for Spanish-made thermodynamic panels that can be installed on a roof or wall as part of a heat-pump system to generate domestic hot water. A system comprises two components — an aluminium black-coated panel that is installed outdoors and a cylinder and compressor unit housed in an insulted case, along with the necessary electronics.

The panel on the roof looks like a solar-thermal panel, but will work night and day in all weather conditions. Panels can absorb solar energy and heat from the air.

Hot water can be delivered at 55°C.

The stainless-steel cylinder is for use on unvented systems and available with capacities of 100, 200 and 300 l. The coil carrying the refrigerant is wound around the outside of the cylinder in a patented design which ensures that refrigerant can never come into contact with the DHW.

The cylinder includes a control panel. An immersion heater is included and programmed two switch on for five hours once a week to bring the temperature of the water up to 61°C to prevent the risk of legionella.

The outdoor panels weigh less than 8kg. Installation requires the services of a refrigeration engineer.
