Elecro In-Line+ Stainless Steel Swimming Pool Heater
The Elecro Inline + model heaters are based around the market leading EVO electric swimming pool heaters and are perfect for use on all types of pools. The digital control offers priority of heating, with timed pump control and has an easy to understand, diagnostic display. Pump interlock is included. This heater will give you accurate temperature control to 0.5ºC and a digital diagnostic display to 0.1ºC.
The decision was made to produce in Titanium for a number of reasons, not only for it's super strength but also for it's outstanding corrosion & erosion resistance properties. The reason that Titanium is so tough in comparison to all other metals is that it is completely non-reactive; this means that the Titanium heater is also suitable for heating acids or virtually any liquids.
The heaters are very easy to install, requiring only final connection to a mandatory separate RCD.No pump interterlock is required. All heaters come fitted with 1½" BSP female threaded adapters for easy connection to all pipework. All heaters are supplied with hose tail adapters for connection to flexible pipework, and heater sizes 12-kW through to 18-kW are also supplied with 1½" BSP unions for connection to rigid pipework.
Titanium heaters are suitable for use with salt water and chlorinated pools

How much will it cost to heat my pool?
Assuming the cost of a unit of electricity to be 6 pence it will cost £4.32 to heat 1000-gallons (4500-Litres) of water from tap temperature to a reasonable swimming temperature. This equation makes no allowance for heat loss.
For Example: an inground 24' x 12' pool with an average depth of 4' holds approximately 7200-gallons. The cost to initially bring the pool to temperature using peak rate electricity will be 7.2 x 4.3 = £30.96 Note that cheap rate electricity is usually billed at less than half the peak rate tariff and could therefore reduce this bill by more than half.
The cost of maintaining the water temperature will be dependent on the level of insulation given by the pool structure, a moderately well insulated pool being used only during summer months may only require 3 hours of top up heat on average per day. At a cost of 27 pence per 1000-gallons (when the heater is sized in the ratio 1.5-kW per 1000-gallons). The religious use of a solar floating cover could dispense with the need for any top up heat being required during warm sunny days.
Please note the above information is for guidance only & running costs will vary from pool to pool and will be dependent on the following main points:
The Level Of Insulation
Water Temperature to be Maintained
Average Ambient Air Temperature
The Cost of a Unit of Electricity

Elecro Swimming Pool Heater FAQ'S
Below we have listed some of the more commonly asked questions and answers, concerning the day to day running of your Elecro Pool heater.
Q - How do I decide which heater I need?
A - The kW output of a heater should be matched to the volume and surface area of the pool, see suggested sizing chart
Q - How long will the heating elements last?
A - The heating elements in all Elecro heaters are of superior construction, offering excellent chemical attack and erosion resistance. Their life expectancy should be many years, provided the Elecro installation instructions are adhered to and water chemistry is maintained within the guide limits.
Q - How long does it take to bring a pool up to temperature?
A - Assuming no heat losses, and a heater sized in the ratio 1.5-kW per 1000-gallons of water: it will take 2 days of continuous running to raise the temperature of a pool from tap temperature to swimming temperature. Heat loss will slow the process particularly during periods of cold weather, i.e. the higher the temperature is to be maintained above average ambient air temperature the slower the heating process will become. The main influencing factor being the level of heat retaining insulation incorporated in the pool shell.
Q - Can I plug my heater in via a standard 3-pin plug?
A - Heater sizes 2-kW and 3-kW can be plugged in via a standard 3-pin domestic plug. Heater sizes 4.5-kW and above require wiring to the property's main consumer unit - the same way a shower or cooker is normally wired. To check the power consumption of your heater please see the tank label of the heater (located on the heaters flow tube) or click on the following relevant link for the power requirements page page of your heater or the heater you are considering: Stainless Steel Swimming
Q - What is priority Heating?
A - Priority heating is when the In-Line+ pool heater can determine that the swimming pool's temperature has dropped below the minimum swimming temperature and then switches the pool's circulation pump on (via the pump control cable) so that the heater can switch on and heat the pool back to the minimum swimming temperature. Once the minimum swimming temperature has been reached the heater will also switch off the pool's circulation pump.
Q - Why does the In-Line+ heater have 2 set points?
A - The In-Line+ heater has been designed to be the most economical electric heater available, by allowing the use of 2 set points you are able to select a higher set point when electricity is cheaper (i.e. off peak) and then a lower set point when electricity is more expensive (i.e. peak rate). It is recommended that the lower set point is programmed to be your absolute minimum swimming temperature, if the pool then drops below this temperature during the day the heater can switch on the circulation pump (as described above) and top up the heat to keep the pool at the minimum swimming temperature.
The Elecro Inline + model heaters are based around the market leading EVO electric swimming pool heaters and are perfect for use on all types of pools. The digital control offers priority of heating, with timed pump control and has an easy to understand, diagnostic display. Pump interlock is included.
