1. Description

The Dura+ Range of Swimming Pool Heat Pumps from HeatPumps4Pools provide enhanced performance over the standard Dura range, for an all year season.

Note that these heat pumps are genuine Duratech heat pumps. Beware of imitation products on the market of lower quality.

Include hosetails for flexi-hose and also 50mm and 1.5″ solid pipe connectors

2. Features

Duratech products are designed in Europe using quality components.

The Duratech Dura Plus Swimming Pool Heat Pumps supplied by HeatPumps4Pools have the following features:-

(the differences from the standard Duratech range are highlighted in bold)

  • High efficiency by using R410a refrigerant gas
  • COP (Coefficient of Performance) of up to 6.5
  • Operate down to -15C degrees
  • Can Heat and Cool the water
  • Dual speed fan for extra energy efficiency and reduced noise
  • Suitable for Koi ponds as well as swimming pools
  • Hot gas defrost cycle to allow operation at lower temperatures
  • Titanium heat exchanger – The use of titanium for the heat exchanger leads to efficient heat transfer without any dangers of corrosion.
  • Digital control panel on all models
  • Green UK & European compliant extra efficient refrigerant gas (R410a)
  • Plastic ABS corrosion resistant casing
  • Refrigerant gas pressure gauge
  • Includes lightweight winter cover (heavy duty winter cover available to purchase)
  • 2-Year parts and labour warranty
  • Designed & Built For Long Life & Reliability

Using high quality materials in the build of the Duratech Heat Pump and a titanium heat exchanger means it is practically “Bullet-Proof” to erosion from Chlorine, Bromine or Salt in the water. Also, the heat exchanger is oversized to improve efficiency and make the Duratech Heat Pump even more cost effective and great value for money.

3. State Of The Art Control

The integrated microprocessor in the Duratech Swimming Pool Heat Pump monitors all the sensors and controls the device without any intervention needed by the user. Electronic display and control with easy operation is standard on all Duratech Swimming Pool Heat Pumps.

4. Quiet Running

The Duratech Heat Pumps use of a highly efficient, low sound compressor, a low noise fan and an oversized heat exchanger on every unit, makes the Duratech Heat Pump extremely quiet in operation. The DURA+10 at 1m distance creates only 51dB(A) and at 10m distance gives only 32 db(A).

The Dura+ range have two speed fan motors resulting in quieter and more energy efficient operation

7. What size heat pump do I require for my pool?

For an outdoor pool in the UK that is kept covered, use the following Duratech guide:-

Duratech Dura Plus Sizing Guide
Max Pool Volume

For a koi pond that is heated all year round with a winter temperature of around 12c and a summer temperature of around 20-22c, we recommend the following sizing:-

Duratech Dura+ Pond Sizing 
Max Pond Volume
Dura+74800 gallons
6800 gallons
9800 gallons
13,800 gallons

(Note: This assumes that the pond is covered in winter and that a temperature of +12c is to be maintained over winter)

However please note that these are the maximum sizes. You should always oversize a heat pump, so we recommend that you choose the next model up in the sizing chart.

Many factors can affect the sizing of a heat pump for your pool. You are therefore advised to Contact Us to get an accurate sizing recommendation for your particular pool.

8. Koi Ponds

Dura+ units are often used to heat indoor pools and koi ponds through the winter due to their ability to operate down to -15C

Bypass KitPlease see our Bypass Kits section section for more information.
Heavy Duty Mounting FeetThermotec-Inverter-Horizontal-rear.jpgThese heat pumps come with rubber mounting feet (picture to follow shortly).

Alternatively you can purchase these heavy duty Mounting Feet.

They come in 2 sizes;

Due to the width of the Dura range of heat pumps – please choose the 600mm feet for all units except the Dura 7 as the width is small enough for this size only.

These raise the unit off the ground by approximately 100mm, and also help to reduce vibration.

Please see our Mounting Feet and Slabs section for more information.

Winter CoverThe unit comes with a lightweight winter cover, however we offer a heavy duty cover which will give you added and extended protection against the winter weather

Please see our Winter Cover section section for more information.

Drip Tray Heater KitThis kit prevents the base of the Heat pump from freezing in the event of severe weather conditions

Please see our Drip Tray Heater Kit section section for more information.

12. Installation

The Duratech Swimming Pool Heat Pump is designed intelligently and exceptionally compact for ease of installation. One of the simple but handy design additions on the Duratech Heat Pump is the integrated flow switch which will sense the water flow and automatically start the heater when the pool pump starts and stop it when the pump shuts off. Simple, but very handy. Also the larger sizes, Dura+22T and Dura+30T come in 3-Phase.

Installation is straightforward. We can provide advice on installing your heat pump. We can also offer an installation service if required.
