BOILERS, PUMPS & VALVES
OGY APPROACH TO NET ZERO Check the water quality.
Impurities in the water can cause scaling and corrosion which will impact on the efficiency and performance of the system and could shorten the life of the boiler and other plant. If planning on integrating a heat pump at a later date, ensure that there is adequate external space and electrical capacity to avoid issues at a later stage.
Where boiler replacement is determined to be the most achievable solution, bespoke-designed boiler rigs enable a rapid, quality installation
heating like heat pumps at a later stage. Examining the condition of the heating system, the plant and hardware, including radiators, will also help future-proof the system. Replace any leaking radiators and ensure any new heat emitters are sized for low temperature heating.
AFFORDABLE, FAST, EFFICIENT HYBRID SYSTEMS When considering the options for boiler replacement, combining a heat pump with a peak-demand boiler is nearly always a fast, efficient and affordable answer. A hybrid approach enables a large portion of the gas to be
decarbonised, while simultaneously reducing risk and overcoming budgetary constraints. A well- controlled system should maximise heat pump contribution and optimise the efficiency of both the heat pump and boiler. Remeha’s Commercial HVAC Manager, for example, provides the option to
cascade up to eight heat generators, either eight heat pumps or boilers, or a combination of heat pumps and boilers in a hybrid installation. An added advantage is that a hybrid solution
requires less electrical demand than a fully-served ASHP in a building, potentially removing the need to upgrade the existing electricity supply. This can be particularly beneficial on projects with tight fixed schedules such as school refurbishment programmes, helping keep them on target.
DEFINED ROADMAP With the 2050 clock ticking, now is the time for owners and managers of existing buildings to define and put in place a project roadmap to lower carbon heat. Whether the initial stage is a boiler upgrade or a bigger carbon-saving leap to a hybrid system, having a defined pathway will help smooth the transition and keep the building on track. And with your chosen solutions provider supporting you along the way, helping you identify the most appropriate approach and supplying all the necessary technologies and expert technical advice, the benefits can be achieved seamlessly, step by step.
