Heating, Plumbing & Renewable Energy Expertise in Dorset
ThermoLoco is an independent heating, plumbing and renewable-energy specialist based in Dorchester, Dorset.
Led by experienced heating engineer Wayne Loco, we provide heating, plumbing, air source heat pump and air conditioning services for homeowners and small businesses throughout Dorset and surrounding areas.
Formerly known as Dorchester Boiler Solutions Ltd, our business has developed alongside the heating industry. What began primarily with boilers, plumbing and traditional central heating now includes modern low-temperature heating systems, air source heat pumps and energy-efficient air-to-air heating and cooling.
Today, ThermoLoco brings that expertise together under one name:

Meet Wayne Loco
ThermoLoco is led by Wayne Loco, an experienced heating engineer with more than 15 years' experience working with heating and plumbing systems and, increasingly, renewable heating and cooling technologies.
Wayne's experience covers traditional natural gas and LPG heating systems as well as modern air source heat pumps, air conditioning and refrigeration-based systems.
This combination is particularly valuable with modern heating systems because a boiler or heat pump is only one component of the complete system.
Radiator outputs, pipe sizing, water flow rates, heating-water temperatures, controls, hot water requirements and correct commissioning can all have a significant effect on comfort, efficiency and reliability.
Rather than simply replacing equipment like-for-like, Wayne's approach is to understand how the complete system works and identify an appropriate solution for the property.
From Dorchester Boiler Solutions to ThermoLoco
Many customers across Dorchester and Dorset will know us by our previous name, Dorchester Boiler Solutions.
As the business developed, the old name no longer reflected everything we did.
Boiler installation, servicing and repairs remain an important part of our work, but our services now extend across complete heating systems, plumbing, air source heat pumps and air conditioning.
The move to ThermoLoco reflects that broader expertise while remaining the same established business and continuing to support our existing customers.
Our approach to heating.
We look at the system not just the appliance.
Good heating-system design involves much more than choosing a boiler or heat pump.
The heat loss of the property, radiator or emitter outputs, heating-water temperature, pipe sizes, water flow rates, hot water requirements and controls all influence how efficiently and comfortably a system performs.
That's why ThermoLoco takes a whole-system approach.
For new and replacement heating systems, this increasingly means designing around lower heating-water temperatures rather than automatically using the high flow temperatures traditionally associated with older heating systems.
Modern low-temperature heating can improve the operating conditions for condensing boilers and is particularly important for achieving good performance from an air source heat pump.
It can also make heating-system improvements carried out today more suitable for the technologies a homeowner may choose in the future.

Heat Pump Expertise
Air source heat pumps bring together several areas of engineering.
They combine a refrigeration circuit with a wet central heating system, electrical components, hot water production and sophisticated controls.
ThermoLoco's experience across heating, hydraulics and F-Gas refrigeration allows us to consider the complete system rather than viewing the heat pump simply as an outdoor unit.
Our heat pump work includes:
Heat loss and heating-system assessment
Air source heat pump design and installation
Low-temperature heating design
Radiator and heat-emitter assessment
Heating pipework and flow-rate assessment
Hot water cylinder selection
System controls and weather compensation
Commissioning
Heat pump servicing
Fault finding and repairs
We can also service and repair suitable heat pump systems originally installed by other companies.
Air Conditioning & Air-to-Air Heat Pumps
Modern air conditioning systems can provide both efficient cooling and heating.
ThermoLoco installs, services and repairs air-to-air heat pump and air conditioning systems for homes and small commercial premises throughout Dorset.
These systems can be particularly suitable for bedrooms, living spaces, home offices, garden rooms and other areas where efficient individual-room heating and cooling is required.
Our refrigeration and F-Gas experience also means we can support these systems beyond the initial installation with ongoing servicing, maintenance and fault diagnosis.
Qualifications, Certification & Training
Professional qualifications and continued technical training are an important part of ThermoLoco.
Our qualifications, registrations and experience span traditional heating, renewable heating and refrigeration technologies.
Gas Safe registered – natural gas and LPG
MCS certified – air source heat pump installation
F-Gas qualified – refrigeration and air conditioning
NAPIT registered
Daikin Sustainable Home Expert
Manufacturer and specialist training covering modern heating and heat pump systems
Wayne has experience working with equipment from manufacturers including Daikin, Mitsubishi Electric, Vaillant, Worcester Bosch and LG, alongside other leading heating and heat-pump manufacturers.
Continued professional development helps ThermoLoco keep pace with developments in heating-system design, controls, regulations and renewable technologies.
Independent, Practical Advice
ThermoLoco isn't committed to recommending one heating technology for every property.
For one home, a modern boiler may still be the most practical choice. For another, an air source heat pump may make considerably more sense. Sometimes the best first step is simply improving the existing heating system.
Our aim is to understand the property, explain the available options and recommend a solution based on what the building and customer actually require.
That could mean replacing a boiler, upgrading radiators and controls, designing a complete low-temperature heating system or moving to an air source heat pump.
A Local Dorset Business
ThermoLoco is based in Dorchester, Dorset, providing heating, plumbing, heat pump and air conditioning services throughout the surrounding area.
Our regular working area includes Dorchester, Weymouth, Portland, Bridport, Sherborne, Blandford Forum, Wareham and surrounding Dorset towns and villages.
For larger heating-system and renewable-energy projects, we may also travel further across Dorset and neighbouring areas.
Being locally based also means our involvement doesn't have to end when an installation is completed. Servicing, maintenance and ongoing technical support are an important part of what ThermoLoco provides.
