Hot Water Boiler Definitive Guide FAQ

The oil fired hot water boiler for sale is a sealed vessel in which heat is applied to produce steam from water.

  • “Fire-tube” and “water-tube” boilers are the two most common varieties.
  • “High-pressure” and “oil fired low-pressure hot water central heating system”, as well as “steam boilers” and “hot water boilers,” are the two types of boilers.

High-pressure boilers usually have more than 15 PSIG pressure. In the strictest sense, a hot water boiler is not considered a boiler. It is a gas-powered water heater. The phrase “hot water boiler” is used because it resembles a steam boiler in many ways.

What Is An Oil Fired Hot Water Boiler?

Water is stored in a tank system in oil fired furnace with hot water, just as in typical electric and gas water heaters. So, whenever you need it, it’s always available to be used on the spot.

There are, however, particular distinctions between oil-fired heaters and heaters that use other fuels. Only dual fuel hot water boiler uses both oil and electricity as a fuel source. There is a burner on an oil-fired heater that produces an oil-plus-water mixture. For heating, an electric spark is generated to the mixture and resultantly it’s ignited.

What Is The Temperature Of Oil Fired Hot Water Boiler?

  • “High-temperature hot water boilers” with temperatures more than 250°F or their pressure exceed 160 PSIG.”
  • Low-temperature hot water boilers have temperatures of less than 250 degrees Fahrenheit and pressures of less than 160 PSIG.”

What Is The Heat Source For Oil Fired Hot Water Boiler?

The heat comes from the combustion of various fuels, including wood, coal, oil, and natural gas. Resistance- or immersion-type heating components are used in electric steam boilers.

Nuclear fission is as well used to create steam, directly (BWR) or through specialized heat exchangers. These specialized heat exchangers are known as “steam generators” in the majority of cases (PWR). HRSGs (Heat Recovery Steam Generators) are steam generators that use heat rejected by other processes, such as a gas turbine.

How Does A Traditional Oil Fired Hot Water Boiler Furnace Work?

A typical oil fired hot water boiler heater comprises numerous parts. These parts include a tank for storing water, a fuel source, fuel lines, and a venting system to remove exhaust fumes safely.

Although, there is no such tank to save hot water for later use. Therefore, this kind of water heater heats up water on demand. On the other hand, traditional water heaters initially dispense water from the tank’s top. This allows the machine to heat up the coming cold water from the bottom of the receptacle until it is needed.

How Does An Oil Fired Hot Water Boiler Work?

You can easily operate a hot water oil boiler, it is quite similar to that of a gas hot water boiler. In this arrangement, the fuel is ignited in the combustion chamber, and cold water is heated by a heat exchanger. This process is done through the mains or cold-water tanks of a traditional design. Yongxing oil fired hot water boiler can be utilized to heat and supply hot water to your home through radiators, faucets, and showers.

Talking about the efficiency of an oil fired hot water boiler it should be comparable to a gas boiler. Oil fired hot water boiler should have an energy rating of 86 percent or A+, according to building codes.

In a warm air system, your furnace heats the air. A blower then sends the heated air up through the ducts and out of vents in your floors or walls. The air gets drawn back to the furnace through a return duct and the cycle repeats.

Finally, the emissions from the combustion of fuel and air exit the system through a flue pipe that runs out of your home through the chimney.

Hot water tank

The effectiveness of a condensing oil fired hot water boiler is usually is 90 percent or higher. Compared to gas, oil is a more efficient fuel. Because oil boilers consume almost the whole heat source and additional gas produced by fuel combustion. It converts more heating energy and reduces waste. This means that every unit of energy you invest will pay off handsomely.

Of course, the primary distinction between a gas and an oil fired hot water boiler is how the fuel is stored. As it is connected to its mains, a gas boiler does not require storage because it has a steady fuel supply. On the other hand, oil fired hot water boiler necessitates a storage tank for oil when we need it.

Now if you are thinking about the installation of the tank, it should be installed on your land, and specific requirements must be observed during installation. The tank’s base must be able to hold the tank’s weight as well as its contents.

You must support the tank with solid ground, such as concrete or paving slabs. These slabs should be a minimum of 42mm thick and extend 300mm beyond the tank’s perimeter. If the tank is close to your home, you’ll need to install a firewall in between the heating tank and your boiler house.

Normally, unique oil tanks are built of plastic and they are quite simple to retain. To guarantee that you don’t face the issue of no oil at any stage, the tank will need to refuel as required. For smaller homes with fewer radiators, the tank may only need to replenish once a year. However, for bigger houses with more radiators, the tank may need to be refilled several times over the winter.

You must have a thermostat in your home that indicates the weather compensation, room temperature, or intelligent controls, just like a gas heating system. To provide reliable temperature readings, a thermostat should be situated out of direct sunlight at a distance from a radiator.

Is The Oil Fired Hot Water Boiler Environmental Friendly?

Oil fired hot water boilers are not as eco-friendly as their other gas or electronic counterparts. Regardless of the fuel used in your oil fired hot water heaters, home heating is available for a significant amount of overall carbon generation. If you heat your home with gas, oil, or electricity, you are not doing so in an environmentally responsible manner.

On the other hand, hot water oil boilers are slightly more efficient than gas boilers. They produce marginally large amounts of heat consuming less amount of fuel. However, if it isn’t maintained and serviced regularly, it might become inefficient over time, just like any other boiler.

Consider utilizing a heat pump to let your house more environmentally friendly and lower your carbon footprint. When used in connection with solar panels, the environmental impact is significantly reduced and substantially more eco-friendly.

How Much Oil Does My Oil Fired Hot Water Boiler Uses Every Hour?

The average oil fired hot water boiler in the United Kingdom requires roughly 17,000 kWh per year to keep warm. Kerosene is used in most oil boilers, and one liter of kerosene provides around 10 kWh of energy. This translates to 1,700 liters of oil used to heat your home and provide hot water over a year.

To begin with, you do not have your heater on all of the time. Most of the 1,700 liters of oil will be consumed in the autumn and winter. For instance, let’s say you have the heater on for almost six months of the year (or 180 days). To calculate the approximate kWh used each day in six months, divide 17,000 kWh (the overall amount of energy usage in a year) by 180 days. This works out to 94.4 kWh.

You need to check how much oil is consumed now that you know how much energy is utilized per day while your heating is on. Now you’ll divide your 94.4 kWh by the number of kWh in one liter of kerosene (10 kWh) to get 9.4 liters. It indicates the amount of oil you’d consume every day if your boiler ran for six months, heating your home 24 hours a day.

So, to get your final solution, you’ll take 9.4 liters and multiply that with the number of hours your heating is on. There are four six-hour lots in 24 hours, so the computation is 9.4 liters divided by four. You now have a total of 2.36 liters. Now, if your heating is on for six hours, your oil boiler burns approximately 2.36 liters of oil every day, or 0.39 liters each hour.

Will Oil Fired Hot Water Boiler Be Banned?

According to the government, from 2025, gas boilers will be prohibited from being installed in newly constructed residences. This is also true for oil boilers. However, this does not mean you must replace your oil boiler if it is in good working order in your existing home. It may cause you to think twice about replacing it when it is needed.

By 2050, the United Kingdom wants to be fully emission-free. Therefore it’s worth thinking about other sources for the purpose of heating your residence.

Oil fired hot water boiler could instead of wood fired hot water boiler in future because of the environment question.

4 Key Things To Consider Choosing The Oil Fired Hot Water Boiler

As per the US energy department, we have four main aspects to review before choosing a new water heater. These are as follows:

  • Fuel

This is an essential factor to consider because energy costs vary greatly depending on your living area. One thing more to keep in mind is that every energy type is not available for every location.

So, first and foremost, determine which fuels are readily accessible in your region: electricity, gas, oil, and propane. Then run a cost analysis to see how much you’d spend each month heating your water with different types of fuel.

  • Cost

Before you make your last buying decision, consider the overall cost of the water heater itself, including purchase, installation, maintenance, and repairs.

Along with the cost analysis, it’s crucial to keep in mind that some water heaters are extremely costly to buy and install upfront. However, they’ll save you a lot of resources in the form of your monthly energy bill once they’re up and running. They are making these comparison figures that can assist you in making your ultimate decision.

  • Efficiency

It’s vital to evaluate the overall efficiency forecasts for different water heaters. You need to do it whether you’re trying to live an enhanced lifestyle with a limited carbon footprint or simply trying to save money on your monthly energy expenditures. These deliberations will assist you in understanding which type(s) would be the best fit for your overall objectives.

  • Size/Capacity

Some water heaters can provide more hot water in less time than others. You can figure out which water heater unit will best meet your demands. You can compare the daily hot water demand of your home and the timing of that demand to the speed and capacity of the water heater.

Scheduling professional consultancies and home/workplace reviews can be pretty beneficial when you’re ready to replace your water heater. This consultation can assist you in evaluating the four components of purchasing a new water heater and identifying hidden cost savings that you may be unaware of.

For heating in a hotel or building, only a few units are connected to achieve a better heating effect.


A Boiler differs from a water heater in many aspects; the most noticeable difference is its appearance. Oil fired hot water boilers are a sizeable box-like item with a system of pipes through which water passes before creating steam.

The water is heated as it travels down the pipes by a gas burner at the bottom, which is hot enough to transform the water into steam. This steam may be pumped throughout the house to heat larger complexes and places like swimming pools.

Water holds heat better than air; therefore, heating it as a heating source is more efficient. The water used in a hot water boiler does not have to be drinkable. However, it can be employed as part of a home’s radiant heating system and run through the walls’ pipes.

Like a water heater, a boiler will have an exhaust system that allows fumes produced by the boiler’s gas burner to escape. Small hot water boilers are solid and consume a lot of energy to operate. However, they can efficiently heat huge pools, hot tubs, and entire complexes.
