Which is Right for Your Home?

Choosing the right boiler for your home depends on your household’s needs and its existing heating system. At Alsto-Heat, our plumbing and heating engineers guide Gloucester and Cheltenham clients through the available options to ensure they get the best solution for their property. This includes identifying the right type of boiler out of the following options:

Our Services
  • Combi Boilers – Ideal for smaller homes with limited space, combi boilers provide both heating and hot water on demand. They don’t require a hot water cylinder, making them an efficient, space-saving option.
  • Regular Boilers – Also known as conventional boilers, these are best for larger homes with multiple bathrooms. They use a hot water cylinder and are compatible with older heating systems.
  • System Boilers – A great option for medium-to-large homes, system boilers are similar to regular boilers but are more efficient. They don’t require a cold-water feed tank and can provide a constant supply of hot water.

When you’re looking for a upgrade and need advice on the best new boiler for your home, Alsto-Heat is here to help.

Boiler Replacements – The Process

Replacing a boiler is a detailed process that demands expertise. At Alsto-Heat, we follow a precise method to ensure your replacement boiler is installed safely and efficiently:

  1. Cut-off Gas & Water Supply – Before any work begins, we ensure the gas and water supplies are securely turned off to avoid any risks.
  2. Remove the Old Boiler – The existing boiler is safely disconnected and removed.
  3. Clean the Central Heating System – We flush your central heating system to remove sludge and debris, ensuring your new boiler operates efficiently.
  4. Install the New Boiler – Your new boiler is expertly fitted, whether you’ve chosen a combi, regular, or system model.
  5. Thorough System Testing – Once installed, we rigorously test the system to ensure it’s operating at peak performance.
  6. Register the New Boiler – As part of the installation, we register your boiler with the manufacturer, ensuring that your guarantee is fully validated.
