Turnbull and Scott have a ‘Heat Loss Calculator’ to help customers determine the amount of heat output they need from heaters to achieve a comfortable or desired temperature in their building space/shop etc.
We get it from you, the customer! We have a Heating Requirements Form (aka Heat Loss Form) that we can send you to complete in your own time and return to us. Once we have this info, we can enter the information into the Heat Loss Calculator.
This stands for Low Pressure Hot Water. LPHW is produced by a Low Temperature Hot-Water Heating System (LTHW system) such as the boiler system you have in your house. LTHW systems are largely used for space heating in our homes, residential buildings, offices etc.
The nominal bore refers to the hollow section of a pipe. It is an approximate measurement across the inside diameter of the pipe i.e. across the ‘hole’ or bore. When we measure pipe, we always work on the inside size of the pipe.
Regardless of the type, heaters are designed and rated to deliver a particular amount or ‘output’ of heat, this is measured and expressed in kW, which stands for kilowatt. A 1.5kW heater would be expected to deliver 1.5kW of heat output into a space. A heater with a higher kW value will be able to deliver a greater amount of heat.
The bar is a widely used metric unit of measurement for pressure and 1 bar equals precisely 100,000 pascals. In a space heating context, water and steam need an amount of pressure applied to move them through pipework. So, you may see a description for a low temperature water heating system supply noted as ‘2 bar’ for example, which is a relatively low pressure.
Convection is one of the three natural methods of heat transfer. This relates to heat transfer in gases and liquids, the others being radiation and conduction.
Convection is the circular motion that happens when warmer air (or liquid)— which has faster moving molecules, making it less dense — rises, while the cooler air (or liquid) drops down.
We offer two types of Over-Door Heater, the wall or ceiling mounted Electric Over Door Heater(ODH) and Electric Recessed Over Door Heater (RDH). Each type has several models that differ in heat output.
Turnbull & Scott offer various types of trench heating product. Some of these main product types use piped water (low pressure hot water) as the heat source and others use electricity.
