What is a calorifier on a boat?
by
Calorifier tanks are otherwise known as a water heater for your boat. They offer you an efficient means of heating water on board for your water system allowing for hot water in taps and showers around the boat. Calorifiers aren’t a fired water heater, like a household boiler.
The calorifier is plumbed into the engine coolant re-circulation system and uses a series of coils inside the tank to heat a body of water contained in the main shell of the tank. This is very much like your standard central heating copper immersion heater in the airing cupboard.
What is the difference between a calorifier and a water heater?
Calorifiers are used generally where hot water demand is not exceptionally high and a slower heat up time is sufficient to satisfy the hot water requirements. They are more cost-effective than direct-fired water heaters and no flues are required, but they can be more more prone to heat loss.
Place the calorifier in position and secure down using it’s four fixing feet. The calorifier is fitted with a temperature mixing valve (1). To set the valve turn anti clockwise to the maximum, this will give a maximum water temperature of 65°C. When the knob is fully closed i.e clockwise it is set to 30°C.

What size water heater do I need for my boat?
Most boat owners choose to store as much hot water as they can in the space available. 10-15 litres of water at 50 deg C is sufficient for a refreshing hot shower. With limited fresh water supplies on board, less than 10 litres is often enough.
How do you pronounce calorifier?
How do you check calorifier flow and return temperature?
When taking the flow temperature from a Calorifier you should push the contact thermometer to a piece of uninsulated and unpainted pipework. If using an infrared thermometer, put a piece of black matt tape onto the pipe. Hold the probe there until the temperature stabilises and record.
What are Calorifiers made of?
What are Calorifiers made of? The ‘U’ tubes are usually made from copper as it has a high thermal conductivity. The copper tubes often have an extended external surface, designed to increase the heat transfer surface. The tubes are joined to a tube plate, usually using a tube expanding tool.
What is a stratification pump?
The installation of a pump which is included in a destratification kit (also referred to as a top-to-bottom recirculation kit) will help to distribute the hot water evenly around the vessel. This means a high average water storage temperature above 60°C can be achieved to kill off Legionella bacteria.
What is DHW on boiler?
The domestic hot water system (DHW) is used to provide hot water for the kitchen and bathroom sinks, tubs and other appliances. The same boiler can provide both water systems as long as both water systems do not mix.
If your boiler is showing the NO CH fault code on the display panel, it means the boiler isn’t recognising the correct operation of the central heating from the boiler. So, this fault code will be displayed when the hot water function is working, but the central heating isn’t.
Should DHW be on or off?
DHW Pump Switch When this switch is off, your unit’s hot water pump is manually disabled, and DHW OFF status light will be lit. This switch may be used when the water heater is being serviced or replaced. This switch must be turned off when water flow from the water heater to the unit is turned off or disconnected.
What is CH and DHW?
Your boiler specs will show you both input and output boiler power. Depending on your boiler type, it can refer to just your central heating (CH) or both your heating and domestic hot water (DHW).
What is a good hot water flow rate?
Ideally, the combi boiler flow rate for a good shower should be at least 12 – 15 litres a minute. The flow rate simply refers to how much water can pass through the appliance to feed taps and showers once the boiler is working.
What temperature should my hot water boiler be set at?
If you’re looking for a good balance of warmth and efficiency, you want to set your boiler to at least 65°C. Setting it a few degrees higher won’t hurt. But it’s important not to set it any lower than that. This is so bacteria in the water doesn’t grow, and cause nasty things like Legionella.
What does flow rate mean? A boiler’s flow rate shows how much hot water it will be able to send to your taps in one minute. However, this all depends on the flow rate of the mains water supply to your home. If the flow rate of your mains is lower than the flow rate of the boiler then it will never reach that level.
Can I leave my boiler on continuously?
Luckily, you can keep your boiler on all day and keep it plugged in and on standby for when you turn on your heating. However, having your heating on all day will cause your energy bills to increase exponentially.
Is 50 degrees hot enough for hot water?
These recommendations state hot water must be stored at 60°C inside the water heater by ensuring, at least once a day, the temperature reaches at least 60°C in the entire tank. Moreover, water should reach the tap at a temperature of at least 50°C.
Is it cheaper to put heating on high for a short time or longer at a lower temperature?
“Having the heating on only when you need it is, in the long run, the best way to save energy, and therefore money,” the website explains. “A timer’s best as your thermostat turns your heating on and off to keep your home at the temperature you set.
Does putting tin foil behind radiators work?
Heat will always travel from a warm place to a cold so installing a reflective foil insulation behind your radiators will result in more heat being reflected into the room instead of being lost through the wall.
