HVAC Services

Project Solvers Planned Preventative Maintenance Strategy (PPM) ensures our customers get the most from their assets. Improving the health and safety of the building users and those who operate and maintain the equipment.  Functions of the equipment that is critical to company objectives. Safeguarding assets, optimizing reliability and availability critical to company objectives.  It can prolong the life of your building infrastructure, boiler and equipment, and can prevent the need for expensive remedial engineering.

When a building’s services are running efficiently, our customers make additional savings in electricity and fuel costs. For apartment buildings, passing those savings on to occupants can also enhance your resident relations. Project Solver offers tailored services so you can select what you need. And when plant comes to the end of its life, we can help with design and installation.

Whatever you need, we offer the complete solution:

Heating, Hot water and boiler plant

Planned Preventative Maintenance is an essential first step in taking care of your boiler plant. Project Solver Ltd can complete an existing maintenance programme, or create a new schedule that exactly meets your needs. We’ll then finalise a condition report before we begin regular maintenance, so you know where you stand by looking at heating controls and making adjustments, we can reduce your fuel costs. If it’s more economic to replace the boiler.

We’ll put together a consultant tender for a new installation. Our gas engineers are trained in both commercial and domestic gas engineering, so they can maintain public, business and residential premises.

Our services include:

  • Gas safety inspections (main plant)
  • Boiler plant & ancillary equipment maintenance

Our gas engineers have met the lengthy competency assessments required to work on gas and are individually detailed on the Gas Safe Register (formerly the Corgi Register).

Project Solver’s engineers have the required competencies for each of these disciplines:
• Domestic
• Commercial
• Laundry
• Catering


The drive towards greener energy sources and sustainability has seen a rise in the use of biomass boilers, certainly using wood chip pellets as the primary fuel source.
Generally biomass boiler installations are used to supplement traditional gas or oil fired boilers. On occasion the opposite is true, with biomass boilers used as the lead heat source supplemented by the traditional systems.

An understanding of the operational and maintenance aspects of these boilers is essential for their continued reliable operation. This covers combustion, pellet delivery, safe storage accounting for carbon monoxide build up, flue and ventilation needs.

Our engineers have both the experience and importantly the manufacturer product training on biomass boilers and systems built up over a number of years.

This combined with our extensive knowledge of traditional gas or oil fired heating plant gives us a unique ability to understand and maintain what can be a complex system with each aspect reliant upon the other. Something that those who are unfamiliar with such interaction often struggle with.

  • Our service includes:
  • Pellet storage, hopper and conveyor inspections
  • Buffer vessel and associated pumps and equipment inspections
  • Fire box inspections
  • Combustion inspections and analysis
  • Control system inspections
  • Flue system cleaning and inspections
  • System Water Quality Analysis
  • Operational checks outside of scheduled service routines

District Heating Systems & Heat Interface Units (HIUs):

The new build residential sector over recent years has seen the predominance in the design and use of an Energy Centre (Central Plant Room) supplying a heat source via a district distribution system to individual apartment HIUs.

This is seen to be able to provide individual apartments with a fully controllable heating and hot water system that each resident can set to meet their own heating or hot water needs. In most instances, it also caters for heat metering, enabling more targeted billing by the Landlord or Agent.

Whilst in principle the design and concept is simple, there are still very important service and maintenance requirements, which can often lead to significant problems if not built into a common maintenance strategy.

Further issues, certainly in the residential sector, involve understanding the point at which the Landlords’ responsibility ends, i.e. provision of a heated water source to the common side of the HIU, and where within the tenancy agreement the user’s responsibility commences. This can often lead to conflict if the Agent or Landlord is unaware of how the system works.

Over a number of years we have built up an extensive knowledge and understanding of these systems, and also invested in manufacturer training enabling our engineers to fully understand the operation and maintenance of these systems.
