Worcester-Bosch Greenstar Heatslave 12/18
The Worcester-Bosch Greenstar Heatslave 12/18 is one of a range of energy efficient oil fired – that is utilising only 28 second burning kerosene – condensing boilers available from Worcester-Bosch. The Worcester-Bosch Greenstar Heatslave 12/18 employs a mild steel primary heat exchanger and a stainless steel secondary heat exchanger which extracts latent heat from the flue gases to convert as much of the fuel consumed into useful heat. This enables the appliance to be 90% energy efficient and therefore in compliance with Part L Building Regulations, which stipulate a SEDBUK ("Seasonal Efficiency of Domestic Boilers in the United Kingdom") rating of at least 86% for new or replacement oil-fired boilers. The Worcester-Bosch Greenstar Heatslave 12/18 can therefore cut domestic hot water and central heating costs by up to 10%.
The appliance "as standard" is suitable for connection to sealed primary water systems, although open vent systems are also a possibility.
The key product details and specifications of the Worcester-Bosch Greenstar Heatslave 12/18 are as follows:
- SEDBUK "A" rated for energy efficiency
- Minimum 12kw maximum 18kW output
- Thermal store pre-heated to temperature set by hot water thermostat so instant hot water
- Floor standing
- Dimensions of 800mm x 600mm x 520mm height x width x depth
- 15 litres per minute flow rate for domestic hot water
- Left, right and rear fluing options for neat unobtrusive installation
- Optional fascia mounted programmer for reduced wiring
- Comprehensive 2 year parts and labour warranty (5 year warranty on primary heat exchanger)
