Boiler Installation in London: A Complete Guide

Choosing a new boiler is a major decision for homeowners, with multiple factors to consider, including boiler type, cost, regulations, and installation services.

Types of Boilers

1. Combi Boilers – The most popular choice, compact, and energy-efficient. Ideal for smaller homes with instant hot water. However, they struggle with high water demand and rely on good mains pressure.
2. System Boilers – Suitable for medium to large homes with multiple bathrooms. They store hot water in a cylinder but require space for installation.
3. Conventional Boilers – Best for homes with high water demand or low water pressure but require both a hot water cylinder and a cold-water tank.
4. Back Boilers & Electric Boilers – Less common; electric boilers are an eco-friendly alternative.
