HEAT PUMPS \u2022 HOMEOWNER GUIDE<\/p>\n\n\n\n

Is your home suitable
for a heat pump?<\/h1>\n\n\n\n

Heat pumps can work extremely well \u2014 but the property, the system design and the installer all need to work together.<\/p>\n<\/div>\n<\/div><\/div>\n\n\n\n

01 \u2014 SUITABILITY<\/p>\n\n\n\n

Is my property suitable for a heat pump?<\/h2>\n\n\n\n

Heat pumps often attract strong opinions. Depending on who you listen to, they are either the future of home heating or an expensive mistake waiting to happen.<\/p>\n\n\n\n

Stories of high electricity bills, cold homes and underperforming systems regularly make headlines. Unfortunately, these experiences can create the impression that heat pumps simply do not work.<\/p>\n\n\n\n

In my experience, that couldn’t be further from the truth.<\/p>\n\n\n\n

Having witnessed thousands of installations over the years, I can confidently say that the vast majority perform exactly as intended. Homeowners enjoy comfortable, efficient heating and many see significant reductions in their carbon footprint.<\/p>\n\n\n\n

\n

So why do some installations fail?<\/h3>\n\n\n\n

The answer is usually not the heat pump itself. Problems typically arise when:<\/p>\n\n\n\n

    \n
  • Installers lack the necessary skills, experience or training.<\/li>\n\n\n\n
  • The original property assessment is rushed or inaccurate.<\/li>\n\n\n\n
  • Heat loss calculations are poorly completed.<\/li>\n\n\n\n
  • The system design is based on assumptions rather than evidence.<\/li>\n\n\n\n
  • Homeowners are not properly informed about how the technology works.<\/li>\n\n\n\n
  • Grant-funded installations become focused on obtaining funding rather than achieving the best outcome for the property.<\/li>\n<\/ul>\n<\/div>\n\n\n\n

    A heat pump isn’t a one-size-fits-all product.<\/h3>\n\n\n\n

    Unlike a traditional gas boiler, which can often mask design flaws by producing large amounts of heat, a heat pump relies on careful design and accurate sizing.<\/p>\n\n\n\n

    A thorough heat loss assessment is therefore one of the most important stages of any installation. Heat loss calculations and system design are critical factors in heat pump performance.<\/p>\n\n\n\n

    The good news is that many of the common problems can be avoided.<\/p>\n\n\n\n

    \n
    \n

    01<\/p>\n\n\n\n

    Check your installer<\/h3>\n\n\n\n

    Verify qualifications, certification, experience and how the proposed system will be designed.<\/p>\n<\/div>\n\n\n\n

    \n

    02<\/p>\n\n\n\n

    Assess the property<\/h3>\n\n\n\n

    A room-by-room heat loss survey should form the foundation of the system design.<\/p>\n<\/div>\n\n\n\n

    \n

    03<\/p>\n\n\n\n

    Understand the system<\/h3>\n\n\n\n

    Understanding controls, temperatures and how the system operates can make a major difference to comfort and running costs.<\/p>\n<\/div>\n<\/div>\n\n\n\n

    This guide primarily considers air source heat pumps. Ground and water source systems have additional design and location considerations.<\/p>\n<\/div>\n\n\n\n

    \n

    02 \u2014 THE INSTALLER<\/p>\n\n\n\n

    Do your homework before accepting a quote.<\/h2>\n\n\n\n

    Choosing the right installer is just as important as choosing the heat pump. A properly qualified installer should be able to demonstrate relevant certification, competence and experience before work begins.<\/p>\n\n\n\n

    \n
    \n

    MCS certification<\/h3>\n\n\n\n

    If you are applying for the Boiler Upgrade Scheme, your installer must meet the relevant MCS requirements. Ask the company to show you its current certification and explain who is responsible for the system design.<\/p>\n\n\n\n

    Electrical competence<\/h3>\n\n\n\n

    Heat pumps require electrical connections and protective devices. Ask who will complete the electrical work and how the installation will be certified and notified where required.<\/p>\n\n\n\n

    Hot water competence<\/h3>\n\n\n\n

    If an unvented hot water cylinder is included, ask who will install and commission it and whether they hold the appropriate qualification.<\/p>\n<\/div>\n\n\n\n

    \n

    Manufacturer training<\/h3>\n\n\n\n

    Ask whether the installer has received training for the particular make and model being proposed. Product-specific knowledge can be important for installation, commissioning and fault finding.<\/p>\n\n\n\n

    Heat loss experience<\/h3>\n\n\n\n

    A reputable installer should carry out a room-by-room heat loss calculation rather than simply replacing a boiler with a heat pump of a similar size.<\/p>\n\n\n\n

    Previous installations<\/h3>\n\n\n\n

    Ask for examples of previous installations and don’t be afraid to ask how the proposed system size, radiator requirements and operating temperatures have been determined.<\/p>\n<\/div>\n<\/div>\n\n\n\n

    \n

    Questions every homeowner should ask<\/h3>\n\n\n\n
      \n
    • Are you MCS certified?<\/li>\n\n\n\n
    • Will you carry out a full room-by-room heat loss assessment?<\/li>\n\n\n\n
    • Who will complete the electrical work?<\/li>\n\n\n\n
    • Will electrical certification be provided?<\/li>\n\n\n\n
    • Who will install the unvented cylinder, if one is required?<\/li>\n\n\n\n
    • Can you provide examples of previous heat pump installations?<\/li>\n\n\n\n
    • What commissioning and handover documentation will I receive?<\/li>\n\n\n\n
    • What warranties are included for the equipment and workmanship?<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\n
      \n

      03 \u2014 PROPERTY ASSESSMENT<\/p>\n\n\n\n

      You should see a proper survey taking place.<\/h2>\n\n\n\n

      If you are considering a heat pump, or already being quoted for one, you should expect to see a detailed property survey. Rooms should be measured, walls and construction assessed, and the property’s exposure, attachments and detachments taken into consideration.<\/p>\n\n\n\n

      \n
      \n

      Measure<\/h4>\n\n\n\n

      Rooms, walls, windows, doors and other heat-loss areas should be properly measured.<\/p>\n<\/div>\n\n\n\n

      \n

      Inspect<\/h4>\n\n\n\n

      Construction, insulation, glazing and the existing heating system should be considered.<\/p>\n<\/div>\n\n\n\n

      \n

      Calculate<\/h4>\n\n\n\n

      A room-by-room heat loss calculation should establish the heating requirement.<\/p>\n<\/div>\n\n\n\n

      \n

      Discuss<\/h4>\n\n\n\n

      Radiators, hot water storage, controls, outdoor unit location and possible improvements should be discussed with you.<\/p>\n<\/div>\n<\/div>\n\n\n\n

      \n

      The heat pump should be selected for the property \u2014 not the other way around.<\/h3>\n\n\n\n

      A good assessment gives the designer evidence to work from. It helps establish the required heat output, emitter sizes, likely operating temperatures and whether improvements to the property should be considered before installation.<\/p>\n<\/div>\n<\/div>\n\n\n\n
