Energy Saving Heating & Ventilation

Ardgartan Hotel, Loch Long


A Kingspan Environmental Aeromax Plus air source heat pump has been installed to heat a 126-bedroom Scottish hotel set in a spectacular location on the banks of Loch Long.

Lochs and Glens Holidays, owners of the newly-built Ardgartan Hotel, were looking for a renewables solution both to reduce the carbon footprint of the hotel and to limit the use of oil and LPG as heating fuels, not least because of their high cost.

After weighing up a range of alternatives, an Aeromax Plus air source heat pump was selected on the basis of their cost-effectiveness and high performance levels.

Aeromax Plus heat pumps use natural heat from outside air to provide central heating (either underfloor heating or traditional radiators) and/or hot water, and are well-suited to working efficiently in cooler Scottish temperatures. They can extract heat from the air at temperatures down to -20°C, making them consistently effective all-year-round, even in exposed locations. They have low running costs and can reduce energy bills and CO2 emissions by as much as 50 per cent.

The powerful 75kW heat pump fitted to the Ardgartan hotel is part of Aeromax Plus’s commercial product range and supplies the hotel’s underfloor heating, providing sufficient output to warm the majority of the ground-floor of the hotel, a total of 992m2.

The heat pump and the underfloor heating system were selected, designed, supplied and installed in a full turnkey solution by local contractors Anderson Floor Warming and Renewables. Michael Anderson, the managing director, advises: “We recommended underfloor heating as the most efficient way to heat the hotel’s ground floor space. Heat pumps work well with this kind of system because of the lower temperatures required by underfloor heating.”

He adds: “The units are compact and easy to install. They are also incredibly quiet, which is important in this tranquil setting, and maintenance requirements are very low.”

Neil Wells, managing director of Lochs and Glens Hotels, comments: “We chose the Aeromax Plus because of its reasonable price and unobtrusive size, plus the fact that it had the Kingspan name attached to it – that was important. The installation was straightforward and although it is too soon to have any operational data, I’m pleased to say that it’s performing very well, as expected.”

Matthew Shaw, area sales manager for Kingspan Environmental says: “This is proof that renewables technology is highly adaptable and can be comfortably installed in even the most remote northerly and beautiful areas. Aeromax Plus heat pumps have a small footprint and a wide range of operational capabilities (from 4kW upwards), so they are suited to all types of properties, from very large hotels, such as this one, to domestic settings where space is limited.”
