Understanding Your Boiler Heating System
Boilers are a common and effective way to heat many homes and buildings, particularly those with older or established heating infrastructure. Unlike forced-air systems that push heated air through ducts, boilers heat water which is then circulated through pipes to radiators or radiant floor systems throughout the property.

How Your Hot Water Radiator System Works
In a hot water radiator system, the boiler heats water to a specific temperature. A pump circulates this hot water from the boiler through a network of pipes to radiators located in different rooms. As the hot water flows through the radiators, they heat up and transfer warmth into the room primarily through radiation and convection. The water, now cooler, returns to the boiler to be reheated, continuing the cycle. This process provides a consistent, even heat that many find exceptionally comfortable, often without the air circulation that can stir up dust in forced-air systems.
Types of Residential Gas Boilers for Lemay Homes
When considering a new boiler for your Lemay property, understanding the different types available is key to choosing the right system for your needs and efficiency goals. Most residential boilers today use natural gas.
- Conventional (Regular) Boilers: These are the most traditional type. They require a cold water storage tank, a hot water storage cylinder, and an expansion cistern, usually located in the attic. They are suitable for homes with high hot water demand or multiple bathrooms. They heat water and store it for later use, providing a steady supply.
- System Boilers: Similar to conventional boilers, system boilers also heat water and store it for later use. However, they do not require a cold water storage tank or separate expansion cistern, integrating many components within the boiler unit itself. This makes them more compact and easier to install, while still providing high hot water flow rates suitable for properties with multiple bathrooms.
- Combi (Combination) Boilers: These are space-saving units that heat water on demand, providing both heating and hot water directly from the boiler without needing separate tanks. They are ideal for smaller properties or those with limited space, offering energy efficiency by only heating water when needed. However, they may struggle to supply hot water to multiple outlets simultaneously compared to conventional or system boilers.
- Condensing Boilers: Both system and combi boilers can be condensing types. Condensing boilers are highly efficient because they recover heat that would normally be lost in the flue gases. This recovered heat is used to pre-heat the incoming water, significantly increasing overall efficiency. They require a condensate pipe to safely remove the acidic water produced during this process. Modern building regulations often require new boiler installations to be high-efficiency condensing types.
Our experts can help you evaluate which type of gas boiler is the best fit for your home's size, hot water needs, and your desired efficiency level.

- Rising Energy Bills: Older boilers are far less efficient than modern units, leading to higher fuel consumption for the same amount of heat.
- Uneven Heating: If some rooms are warm while others remain cold, it could signal boiler inefficiency or circulation problems often best resolved with a system upgrade.
- Strange Noises: Kettling (a rumbling sound), banging, or whistling can indicate significant internal issues.
