Are you looking for information about- Biomass solid fuel wood pellet boilers, solar panel heating systems, heat pumps, appliances and parts, to remove dependence on heating oil or gas.

What is Biomass Fuel?

Biomass is defined as ‘material, other than fossil fuel or peat, which is, or is derived directly or indirectly from, plant matter, animal matter, fungi or algae’.  Examples of fuels that often meet this definition include (but are not limited to):

  • Wood logs, chips and pellets
  • Straw and agricultural residues
  • Food waste
  • Paper/ pulp residues from the paper manufacturing process
  • Biomass residues from the food processing industry
  • Sewage sludge

What Are Biomass Heating Systems?

Biomass heating systems use agricultural crops, wood and waste wood products to produce heat and electricity with less effect on the environment than fossil fuels. This type of energy production has a limited long term effect on the environment because the carbon in biomass is part of the natural carbon cycle; while the carbon in fossil fuels is not, and permanently adds carbon to the environment when burned for fuel.

Biomass Boilers can run on a variety of fuels and run very efficiently on pellets. These are made from a wood material which is dried and compressed to a low moisture level with no additives. The resulting fuel has a high calorific value or heat content and is clean, burning easily and efficiently to give you constant heat.
Pellets allow for the fuel to be stored in a hopper and fed automatically into the boiler.

Why Verner & Ponast

That is a good question!  How many people have heard of them before now? Not many I would wager and we certainly hadn’t before the middle of 2012. We came across Verner while looking for an appliance for our own home, one which would provide all of our hot water and heating requirements and free us from the gas bill. I suppose this is the same reason why many of you are reading this now. Of course we looked to our UK market first but soon decided that while we are a great nation of engineers and manufacturers, we simply don’t make anything even remotely close to what we were looking for, so with trepidation we decided to look further afield.

We did our research and came across Verner and we liked what we saw. They didn’t have distributors in the UK but were willing to sell us one directly as we are a well-established business both retailing and installing heating appliances. Buying something unseen is a leap of faith by anyone’s standards but we stumped up the money and waited for the delivery which happily took only one week, thankfully it came well packaged and in one piece.

To say that we were impressed is an understatement. In this day and age of cutting corners and increasing margins it is rare to come across a company prepared to stick to sound engineering principles and manufacture a product intended to last. That was obvious when we tried to move it – it’s heavy! As engineers ourselves we could appreciate the finer details such as a bearing on the keep for the door catch and beautifully tig welded stainless steel fittings with no sharp edges.

Our family holiday was spent in the Czech Republic, four days of which were spent with Verner at their manufacturing facility in Cerveny Kostelec. Verner is run by the Verner family, all of whom are engineers and are completely hands on in the company, it felt good to be talking to a good old fashioned family firm with a modern outlook and moral values similar to ours.

The UK needs well-designed heating products which deliver their promise which is why we struck a deal to become sole distributors for Verner in the UK.

We know a good thing when we see one. That is why we know that we will be hearing much more about Verner & Ponast in the future.

Solar Thermal

What Are Solar Thermal Heating Systems?

Solar thermal heating systems use heat energy from the sun to increase the temperature of the liquid within the solar panel. This liquid is then pumped through a  heat exchanger withinin a water tank (sometimes called an accumulator), transferring the collected heat to the water in the tank for your hot water needs.
By fitting Solar Thermal panels during the summer you could save all of the costs associated with heating your domestic hot water and in winter the biomass boiler will top up what is needed.   No need to use fossil fuels at all.


Why Choose Solar Thermal?

Heat water for your home using energy from the sun.

No need to use fossil fuels or electricity in the summer when you would prefer not to use your biomass boiler.  Solar thermal panels/collectors use free heat from the sun to warm domestic hot water.  This is the perfect way to compliment the use of your biomass boiler during summer months.

The benefits of solar water heating

  • Hot water throughout the year: the system works all year round, though you’ll need to heat the water further with your biomass boiler during the winter months.
  • Cut your bills: sunlight is free, so once you’ve paid for the initial installation your hot water costs will be reduced.
  • Cut your carbon footprint: solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.


Savings from Solar Thermal

Solar water heating systems can achieve savings on your energy bills.  Based on an industry recognised calcualtion 10% or your total fuel bill will be due to the production of hot water.  For example if your annual fuel bill is £1,500 the 10% proportion used for heating domestic hot water would be £150 and this would be the annual saving if you fitted solar thermal.

You may be able to receive payments for the heat you generate from a solar water heating system through the government’s  Renewable Heat Incentive.

Why a CTC Regulus Heat Pump?

In the sphere of high-quality heat pumps CTC Regulus ranks among the leading suppliers. Heat pumps
supply from us, unlike from our competitors, combines all the demands that are expected
to be met by a heat pump:
 High energy savings
 Very quiet heat pump operation
 Top quality
 Excellent parameters
 Long-term customer care

 Remote monitoring via WiFi

High energy savings
We put emphasis on the right technical design of the entire heating system making the heat pump operate
more efficiently and economically, giving a long service life. Moreover, our systems can offer a combination of
further heat sources like solar thermal systems, biomass boiler stoves and common boilers.
Savings achieved this way are even higher.

Very quiet heat pump operation
Noise level has never been high for CTC Enertech heat pumps, however our designers of the new heat
pump generation succeeded in reaching such low values that we have become market leaders in this area.

Top quality
We offer heat pumps made by CTC Enertech, a traditional Swedish company who has been
manufacturing heating technologies since 1923. Heat pumps have been produced by the company for
over 30 years. CTC Enertech is the first manufacturer ever to produce air-to-water heat pumps.
CTC and Regulus are leaders in their engineering field.

CTC Heat Pumps have been granted the European Quality Label for Heat Pumps (Q label) which
guarantees, first of all, that the performance figures are true, that the supplier is reliable.
CTC Heat pumps are characterized by a long service life, even under harsh climatic conditions in
Scandinavia. That is one of the reasons why these heat pumps rank among the best in Europe.

Excellent parameters
CTC Enertech puts emphasis on innovation. The latest series of heat pumps excel in operating
parameters compared to competitors’ products:
 High flow temperature, up to +65 °C
 Heat generated even under very low outdoor temperatures, as low as -22 °C for air-to-water
heat pumps
 System with a CTC heat pump is rated with the highest efficiency class, A+++
 Compact build – a sealed refrigerant circuit, easy installation
 Very quiet operation

Long-term customer care
It is very easy to buy a heat pump from a manufacturer. However, it is much more difficult to select
the right heat pump type and related heating system elements suitable for a specific situation.
Many customers already have or intend to buy a solar thermal system, fireplace, boiler
which are included in our design, so that the whole heating systems works in an effective
and efficient manner.
Once a heat pump is installed, a warranty service follows. Our system is ready to be extended if required
in the future (solar thermal system, biomass boiler stove.).
Further we offer remote monitoring of your heating system for service monitoring of your heat pump
and heating system operation.

Types of heat pumps
Heat pumps are manufactured in two most common types:
Air-to-water heat pumps
Air-to-water heat pumps draw energy from the ambient air. The latest types of heat pumps work
under very low outdoor temperatures, as low as -22°C. They are manufactured in compact design;
the entire heat pump is housed being in one compact unit.
Ground-to-water heat pumps
Ground-to-water heat pumps draw energy from the ground (they are independent of the ambient air
temperature). These heat pumps utilize heat either from deep bores or from shallow underground pipe loops
(laid horizontally below frost line).  Ground-to-water heat pumps are placed indoors and are manufactured in two versions –
a heat pump alone, or a heat pump with a thermal store for space heating support and hot water heating.
Controllers and other boiler-room components are housed within a neat, fridge-sized case.
