The Ideal Logic Condensing Gas System Boiler range is ideal for a variety of property sizes with multiple bathrooms and a high demand for hot water. The Logic Gas System Boilers are a light weight unit with cupboard fit dimensions for out of sight installation providing the user with flexibility when deciding where to install the boiler. Also the Logic Gas System Boiler features a user friendly digital display with simple diagnostics to help make servicing and maintenance quick and easy. Plus the Logic Gas System Boiler is a condensing boiler able to reclaim latent heat from the flue gases before they are expelled into the atmosphere and the heat is used to help reduce fuel consumption which means lower gas bills and reduced carbon emissions.
At Boilers2go we recommend the Ideal Logic 18kw Condensing Gas System Boiler for small to medium size properties with more than one bathroom and a high demand for hot water. Also the Logic 18kw Gas System Boiler has an impressive energy efficiency of over 90% giving it a SEDBUK 'A' rating the highest official energy efficiency rating in the UK. In addition the Logic 18kw Gas System Boiler comes with a 2 years manufacturer's parts and labour warranty for added peace of mind.
In a closed central heating system water cannot be compressed so any increase in the volume, created by an increase in temperature, needs to be accomodated. This is done with the use of an expansion vessel, when the water in the system is cold the pre-charge pressure of the system forces a diaphram in the expansion vessel against the tank towards the inlet. As the temperature increases the expanding water volume pushes against the diaphragm creating additional volume for the water to enter the expansion vessel. As the temperature decreases the pre-charge pressure forces the water from the expansion vessel back into the central heating system. This maintains a constant pressure within the central heating system and helps to reduce energy and water consumption.
