Features Benefits
Pre-packaged hot water and heating in one cabinet Quick and easy to install, saving time onsite
Combined space and domestic hot water heater No need for separate appliances, saving space and particularly suitable for smaller plant rooms with space constraints
Compact and lightweight design that can be split into two parts Easy to manoeuvre within a building; suitable for retrofit applications where plant rooms and/or access space may be limited
Almost instantaneous hot water generation of up to 2,240 litres/hr and small integral 300 litre storage tank Reduction in standing heat losses and levels of hot water generation, saving energy and costs
Up to three gas-fired heat exchangers Built in redundancy ensures a constant supply of hot water or heating
Natural gas or LPG Available for off mains gas areas
ErP rated internal pump and circulators Improved operating efficiency and performance
WRAS approved Complies with the Water Supply (Water Fittings) Regulations and Scottish Byelaws
Immersion heater boss Improved reliability – hot water back-up
