In the 1960s and 70s a conversion took place in the UK from the use of town gas (which was mostly produced from coal and oil) to natural gas. Earlier this year, Worcester Bosch revealed a prototype of a boiler that could be converted from operating with natural gas to hydrogen....
“Once a month or so, they can shut off the circuit breaker ... open the front panel, and rinse out the screen,” he said. “Clean out as much as possible with Lysol wipes or dishwashing liquid and warm water. Or h...
Boilers can be fueled with either natural gas or oil, a boiler's efficiency is measured in AFUE Condenser A condenser is the outside portion of air conditioning system. It is responsible for the transfer of heat out of air, a condenser condenses refrigerant from vapor to liquid. ...
Heat Pump Efficiency by Generation By the late 1960s, when the first Generation X babies were born, most new homes in North America had central air conditioning.2 It wasn’t until the 1970s oil crisis that heat pumps became a more popular choice for heating and cooling homes.3 Heat pumps...
–Michael Smith,customer Bought an older home and just wanted to learn how our heat pump/gas furnace worked together. Jeffery gave me a tutorial and then started checking our entire HVAC system. While inspecting our gas furnace he noticed water where it wasn't supposed to be; upon further ...

Traditionally, the sensible heat of water-based working-fluids is low, while that of oil-based working-fluids is higher, but the load capacity is relatively low. In order to find a balance between the two, an optimal stirring working-fluid should be selected. In this study, an experimental...
The table also accounts for the units added later on to existing heat pump plants. Numerous heat pumps were installed mainly in Sweden in the 1980s, and this was caused, at the time, by a temporary surplus of electricity produced by newly-built nuclear power plants. Given the limited ...
Therefore, if compressive loading were to be considered for an SMA heat-pump, special attention should be paid for the geometry, putting into consideration the effectiveness of the heat-transfer between the material and the heat transfer fluid. 8.4. Application Elastocaloric refrigeration can cover a...
