Norton Park Hotel biomass system

Norton Park Biomass Installation

Current System

Current system comprises of one boiler room to supply the entire hotel and manor house with heating

and hot water. The system comprises of 3 x 500kW oil boilers situated in their own building.

Current control system

The current system has very little control with no BMS system in place. During the winter period, the

boilers run constantly to provide adequate heat to the hotel.

We recommended that a BMS system is installed to greatly increase efficiency of the system.

Current running costs

The oil used from January 10 – December 10 inclusive was 243,846 litres of oil.

This equates to approximately £158,500 in the year if the oil based at 65p per litre

Proposed system

Boiler Location

Proposed system to be fitted in an adapted 40ft containerised system incorporating boiler system and

controls, along with the pellet fuel storage. The image below is a scale 3D rendition of the container

system sited next to the boiler room. Boiler system is con-sealed from the public and provide no access

issues, fuel delivery is straight forward due to the immediate access from the car-park. To site the boiler

in the best location for operation, the LPG gas tanks for cooking would require moving to a different

location

Boiler Plant

System proposed is manufactured by HDG Bavaria in Germany.

HDG have been a leading force in the development of split wood boilers and pellet boilers over the last

three decades. HDG’s many years of experience is the basis for the quality of their products and the

key to success with customers.

The proposed boiler is an HDG Compact 200. If you wish to see one fully operational, we can organise

a visit to Euroheats training facility where an HDG Compact 200 is heating the entire office, warehouse

and training facility.

The HDG Compact 100-200 is an automatic wood heating system for burning wood chips, shavings

and pellets for outputs of 100 to 190 kW. This makes it particularly suitable for use in agriculture and

forestry, commercial businesses, shared heating systems, hotels and larger buildings.

Suitable for wood chips (up to 65% wood moisture, medium chips of 3 to 5 cm max. G50), shavings and pellets

Patented back-burning protection with rotary feeder Highly convenient with automatic cleaning and ash removal High quality combustion technology with air-cooled, moving stepping grate

The 3D rendition below is a cut out diagram of the boiler system and pellet store within the container.

The system comprises all feeding equipment, boiler, ash removal system and cyclone chimney system

to meet DEFRA approval. All equipment is MCS approved.

Estimated fuel use and costs including RHI payments

The following table shows the estimated payments for RHI and relative fuel costs. The costs are based

on the boiler running approximately 19 hours a day, 365 days a year

The annual RHI is calculated at £42,779 a year.

Using an oil price of 6.5p per kW, by use of pellets, savings is approximately £51,400 per annum.

Bulk pellet ordering will reduce the cost per tonne depending on the supplier. Forever Fuels based in

Berkshire apply an accumulation discount through the year. The more pellets ordered in the year, the

better the discount. For over 100 tonnes the costs are down to £143 per tonne. This would be met very

easily when combined with other hotels in the chain. For pellet deliveries, the container holds 12 tonnes

of pellets so there would have to be approximately 25 deliveries in the year.

Servicing/ Staff training

As part of our ongoing system maintenance we provide service contracts to ensure smooth operation of

the boiler and equipment. The service contract is £190 + VAT per month, including parts.

We can provide training days for staff currently involved in the maintenance of the heating system. This

will give them a clear idea on the operation of the boiler and will have adequate knowledge to fault find

if required and maintain the boilers. Staff training is included in our costs.

Finished Installation.

The Hotel decided to remove trees adjacent to the boiler house to prevent the need to remove and re-

position the LPG tanks used for cooking. This was a more cost effective approach.

Fuel savings are approximately £750 per week during summer use.
