Neptune patio heater review: The "Dragons Den" patio heater

The Neptune patio heater was first seen on BBC's Dragons Den series where it was pitched by Eddie Middleton. The Neptune is manufactured from a tough steal and coated in a weather proof heavy paint finish. The unit is virtually the same as the cheaper model the Mercury but has a light on the top which can be set on permanently or via the PIR. The PIR sensor is for energy saving so when there is no movement the Neptune will switch off the heater and the light. When it detects movement it restarts on its last setting which is useful when it is used on patios where people are coming and going. The Neptune also has a level safety switch so if it gets knocked over it will switch off. When the unit is tipped back to move on the caster style wheels for example the Neptune will switch off. The remote controller is a circular share with a magnetic back so it can be stuck anywhere on the side of the patio heater which is a good feature.

What's in the box?

On arrival the product comes in a box (almost like a coffin) in parts which need assembling. There is no need for specialist tools as most of the nuts and bolts are wing nuts. It is just a case of putting the body of the unit onto the base part and the light assembly just pushes into inserts on the top. No specialist required. A hand held magnet controller with batteries is supplied.

Heater Settings

The Neptune has two heater setting which are 1.15kW (one bar switched on) and 2.3kW (two bars switched on). Both heaters are a filament within a glass tube almost like a fluorescent light tube. The heat can be felt in a radiant fashion from around 4-5 meters away and is an enjoyable heat to be near. The whole idea of the Neptune genera of patio heaters is the instant heat without the smell of burning fuel or the inconvenience of having to get fuel/gas. It does it fantastically.

Air source heat pump boiler options for the UK market

Air source heat pumps are a easy way of replacing a existing fosile fuel heating system. Off the gas grid locations are particularly expensive to run especially when oil is used and there is always a issue of a big oil tank which needs to be sited on the property which can be unsightly. Air source heat pumps have a outdoor condensing unit (heat collector) which collects the heat from the ambient air. These can be fixed on a wall or level and generally look exactly the same as a air conditioning system outdoor condensing unit.

The Basics :

The outdoor air source condensing unit comprises of a refrigeration compressor, a condensing coil (Ambient air exchanger), fan and water heat exchanger where collected heat from the ambient air is transferred to the water. Most air source heat pumps run on R410a refrigerant gas which has a maximum heat to water transfer temperature of around 60 DegC. Other machines run on R417a which is a replacement for R22 which is now not in use (as from 2010). R417a machines maximum heat to water transfer temperature is 55 DegC, both Gases require a booster electric heater to take the water temperature above 65 DegC to surpass the legionnaires breeding temperature. There is one machine which uses R410a and reaches 65 DegC, this is the Daikin Altherma Heating Only Air Source Heat-Pump Boiler System high temperature unit. This system can be very expensive. Other options are the Sanyo CO2 system which reaches 80 DegC comes as a complete system but uses the heat store principle where a water tank which has multiple coils is used as a central store of heat.

Main manufactures and machines:

Trianco Activair Air Source Heat-pump S500 (5 KW / 18000 Btu) for DHW (basic non-inverter type which requires a heat store water tank to transfer heat to)

Hitachi AquaFree air source heat-pump boiler RWM 3.0FSN1E (10 kW / 33000 Btu) (mainly underfloor application)

Daikin Altherma Heating Only Air Source Heat-Pump Boiler (The best money can buy, works down to -20 DegC)

Hitachi RHUE-3AVHN "all in one" air source heat-pump boiler (8.2 kW / 28000 Btu) DHW/heating ( all in one system with no need to heat store)
