Pre-Heaters for Boats / Marine
Why heat a Boat?
Whether you navigate by power or sail, an Espar diesel-fired heater will keep you warm and comfortable, no matter what the weather or season.
Available in a wide range of thermal outputs to closely match your on board heating needs, Espar heaters are compact, convenient, economical to run and time tested for safety - with over 30 years of successful installations.
Every Espar heater is engineered for years of reliable use, and backed by at least a full year parts and labor warranty. An international network of distributors and dealers ensures prompt, courteous service wherever you go. So set your course for boating comfort with reliable, on board heating systems from Espar.
Why Heat Power Boats?
Modern motor yachts offer a high level of luxury and comfort, and a warm and cozy environment will be a priority. Espar air or coolant Heater systems fit virtually any type of motor yacht. For example, an Espar coolant system installation can be integrated into your domestic hot water system and give a supply of hot water at all times.
Espar Air Heaters are normally installed in the engine area with hot air ducted to the cabins via flexible tubes. All you see are the discreet outlets in the cabins.
Diesel fuel is drawn directly from the main tank with a separate fuel metering pump; this pump is included with your kit. For boats with gasoline engines it is recommended that you consult your dealer for guidelines and installation instructions.
If you have a gasoline fired engine a diesel heater is recommended using a separate tank to hold the diesel. Fuel usage for the heater is such that only a small tank is needed.
Espar heaters can suit boats up to 95ft through multiple heat and zone heating, whilst offering the latest in power and space saving designs.
Why Heat Sailboats?
In a sail boat, space is at a premium. The compact size of an Espar unit reflects this with the heater usually being fit in a stern / cockpit locker and the exhaust being led away to the transom.
The warm air duct system is led to the cabins behind panels and through interior lockers. All that can be seen are the outlets in berth/seating fascias. The ducts are kept as short as possible to maintain an efficient air flow.
Very often only one outlet is necessary in sailboats up to 32ft. The strength of the outlet hot air flow is sufficient to convect throughout the boat.
As ducts pass through interior lockers, natural surface heat loss creates useful drying compartments. This surplus heat is also doing much for heating those hidden corners beneath the cabin floors.
Fuel is drawn from the main boat tank and actual consumption is so small it does not materially affect the capacity of fuel carried for the engine.
A battery connection is necessary to drive the initial ignition, fuel system and main air fan. However, Espar units are designed to offer a balance of economic electrical draw with optimum heat and air power performance.
New compact models such as the AIRTRONIC 4 offer integrated electronic control (no separate control box required), automatic boost heat level, self-regulation across a number of heat levels and extremely low power consumption.
