Hydronic Heating Boilers

We stock, supply and install the Thermalux range of boilers.

Overview of the Hydronic Heating Boilers

These units are wood fired hydronic boilers and are designed to heat a lot of hot water that can be used for Inslab Heating or heating Radiators (or a combination of both)


Dynamic 2500

The smallest Boiler in the range. This dedicated Boiler can be installed as a stand alone Boiler to heat up to 200 square metres (20 House Squares) or as an add-on to a Thermalux cooker to provide additional heating. The Dynamic 2500 is a very compact, competitively priced unit which because of its size may require refuelling more frequently to achieve the best results. This unit can also be successfully installed in a Laundry area, turning it into a perfect drying room..




Dynamic 3500

A versatile dedicated hydronic heating boiler with cleverly designed waterways and smoke paths to gain the maximum heating from its compact size. Its design allows the boiler to be heated on all sides to give maximum efficiency and heat output.

With its clean lines and a glass door fitted, the unit is perfectly suited for the living area of any home where it can provide space heating to the room in which it is located, as well as central heating to the rest of the house.


There is the added benefit and charm of viewing the magic of the flames through the glass door or enjoy a delicious cup of coffee brewed on the cook top. The Dynamic 3500 is also available with a solid firebox door for installation in a garage or plant room. The Dynamic 3500 is recommended for heating areas up to 300 square metres (30 House Squares).




Belvedere 5000

Currently the largest in the dynamic boiler range, the Belvedere incorporates some innovative changes to boiler design and operation & will provide up to 5Okw of heat.

The Belvedere has a large symmetrical firebox which will continue to give high output temperatures with extended times between refuelling. Although primarily designed for installation in a plant room, it can also be installed in a living room and a glass door is available on request for an additional cost..


The Belvedere is the best choice for in-floor slab heating as its high output, spacious firebox and considerable water jacket capacity, enables the initial temperature rise required for in-slab heating.

The Belvedere comes standard with both manual and automatic air-flat control, self closing draught diverter, and temperature sensor.

The Belvedere is available as a “Bare” unit where the installer provides the pump and controller at time of installation or “Fully Plumbed” with integrated pump and easily accessible and adjustable Thermostatic control. In this format only the flue and flow and return pipes need to be connected.

Standard Features

of the Thermalux Dynamic Boilers

All Dynamic Boilers come standard with a grate and self scooping ashpan, separate firebox and ashpan door, separate damper and air controls (automatic and manual control on The Belvedere 5000) and all use a standard 150mm (6″) flue assembly.

All Dynamic Boilers contain mild steel waterways and require the addition of a water conditioner. We recommend the addition of “Thermablend” long life boiler conditioner and corrosion inhibitor to maintain the system in optimum working condition.

If connecting a Dynamic Boiler to a domestic hot water service, a heat exchange system must be used. For additional information on your central heating requirements contact your Thermalux dealer or Wise Living Products direct.


Linea 20

The Linea is the pocket rocket of glass fronted hydronic heating boilers. Despite its compact size, the Linea packs quite a punch, delivering 20+ kilowatts of heat to provide comfortable winter warmth for up to 200 square metres of living area in the average home, and even larger areas in new homes with their significantly improved insulation qualities.


The Linea provides the home owner with all the advantages associated with wood fired central heating, such as competitive running cost, quiet, draught free, even warmth along with the rich heat only a wood fired heater can bestow. The charm of the flames dancing in the fire box is an added benefit which helps make for cosy winter nights.

Although the Linea delivers most of its heat via hydronics, either by way of radiators, in-floor coils or occasionally by fan convector units, the glass door gives it the appearance in the home of a conventional solidly constructed combustion heater.

The glass door is designed in such a way as to allow combustion air to flow over the glass to help the glass self clean.

Primary air control at the base of the door delivers a turbo charged effect to the combustion chamber which allows the Linea to deliver potent heat from such a compact unit.

Once closed down the fire will burn happily for hours unattended providing effective overnight burn and soft background warmth for its owners.

Although the Linea has primarily an ash bed styled fire chamber, a modified ash pan area has been incorporated into the design to allow convenient ash removal at any time. As with most Dynamic series boilers, the Linea also allows for partial control of the flue gases keeping the flue temperatures lower and increasing the units efficiency and heating ability.

The top surface of the free standing Linea can be utilised as a cooking surface. You can always have a kettle on standby or brewed coffee at the ready.

The standard Linea is finished in sleek metallic black. Other colour finishes are available on request.




Sophel Combination Boiler

The Sophel range of hydronic heating boilers are true to the wise living philosophy of all Dynamic series boilers.

The Sophel combines the ambience of a super large glass front heater with the flickering flames of a real log fire and the wonderful even warmth that only wood fired hydronic heating can provide.


This combined with the cost savings gained through the burning of natural renewable fire wood – an important consideration with renewable energy playing such a vital role in today’s world. It is worth noting that fire wood is also condsidered to be green house neutral.
