Mr Plumber are well equipped and experienced in the sizing, sourcing, placement installation and maintenance and repairs of evacuated tube solar hot water units, solar panel hot water units, solar heat pump hot water systems, gas hot water heaters or traditional electric hot water systems.
Evacuated Tube Solar Explained
Evacuated tubes consist two glass tubes fused at the top and bottom and sealed. The space between the two tubes is evacuated to form a vacuum. A copper pipe (called a heat pipe) generated absorbs the heat collected in the tubs. The heat pipe tube meets a copper manifold at the top of the unit and the heat is transferred to the manifold. The manifold is connected to a pipe pumping water through the manifold thus heating the water during the day when solar radiation is present. The hot water is then stored in an insulated tank for use during the night hours. When hot water is used, the tank if refilled with cold water and the process continues
Unlike traditional flat plate solar collectors which rely solely on solar radiation. The evacuation tube can extract the heat out of the air on a humid day and doesn’t require direct sunlight. Due to the vacuum inside the glass tube, and its larger collection surface area evacuated tube solar is the most efficient type of solar unit due to its ability still work when the sun is not direct – such as when it’s early in the morning or in the late afternoon.

Solar Heat Pump Explained
A heat pump uses renewable energy to heat water in a different way to traditional solar hot water systems. Heat pumps collect heat from the ambient air, a fan draws air into the unit where the air meets an evaporator containing a refrigerant gas that has a boiling point of -260C. The air is far warmer than the refrigerant, therefore the refrigerant is then converted to a gas and boils. This gas is compressed and as a result, a great deal of heat is generated. The heat exchanger transfers heat from the gas pipes to a water tank. Once the heat transfer takes place, the refrigerant cools down and turns back into a liquid and the cycle repeats itself.
Heat pump hot water can save you a lot of money on your hot water bills as they use approximately one third the energy of an electric water heater. Additionally, there’s generous rebates available making them an extremely economical option!

Gas Hot Water Explained
Instantaneous Hot water
Tankless continuous flow water systems are the most installed type of gas hot water heater. The biggest reason is due to the fact that they never run out of hot water. Instantaneous units produce hot water on demand by sending water through a gas burner. A thermostat then controls the temperature of the output to the desired temp. The result is instant hot water without using the energy to store and maintain hot water and reheat several times before use.
Gas Storage Hot Water Unit
Gas storage systems create hot water on a similar principle to instantaneous, however the water is created and stored in a large storage tank. Gas storage units are generally cheaper to run than electric storage hot water systems.
Rinnai Continuous Flow Summary
Electric Storage Hot water units heat water inside an insulated tank using an electric element. They can be made more efficient by wiring the unit up to an off-peak electrical circuit. Electric storage are the least efficient type of system to run, and with rising electricity prices, also the most expensive to run. However they are the cheapest initial investment and easiest and quickest to install due to the ability to replace like for like without re working any plumbing pipework.
