When choosing your boiler think about space available for the boiler and associated cylinders, tanks and also the system demands that are required. Check energy rating labels and compare running costs. Boilers need to be serviced regularly to ensure efficiency with a requirement to meet Building regulations and it is mandatory that all this type of equipment is installed by correctly registered engineers like Battersea Plumbers . Boilers are available for all types of fuel including oil, gas, LPG, solid fuel and of course electricity. Gas is the most common followed by oil and LPG for homes with no gas supply.Below is a basic guide to different boilers available:1). Conventional Boiler. Uses a heat exchanger to heat the water just like a gas ring under a kettle. Most conventional boilers will work with fully pumped open vented systems, with a few working with existing gravity hot water systems.2). Combination Boiler.Also known as “Combi” boiler this is a central heating boiler and multi point water heater in one. It delivers hot water from the cold water mains on demand to taps around the house. Saves lots of space having no tank or cylinder. Some boilers store a little hot water in readiness for use. Most can be used with gas or LPG though oil fired options are also available.3). Back Boiler.Another heat exchanger situated usually behind a gas fire. These are older with no real possibility of fitting in new properties. SW11 Plumbers are skilled and qualified to carry out boiler installations.4). Condensing Boiler.This type of boiler is designed so that returning water from the heating system cools the flue gases. Known as “High Efficiency Boiler” they work best with lower system water temperatures giving significant efficiency. These boilers are available for use with either gas, LPG or oil. Combi-Condensing boilers are available also.
