Mistral Mega Combi Plus Non-Condensing Oil Boiler

Mistral Mega Combi Plus

The Mistral Mega Combi Plus Non-Condensing Oil Boiler is a high-capacity oil-fired combination boiler designed for larger homes, country properties, barn conversions and commercial-type heating installations.

Available in 41–50kW, 50–58kW and 58–70kW models, the Mega Combi Plus provides central heating and domestic hot water from one large-capacity appliance. The non-condensing range has a B heat class and an XXL-B water class. (mistralboilers.com)

A major advantage of the Combi Plus specification is its integrated 230V electric immersion heater within the boiler’s hot-water store. This provides a backup domestic-hot-water supply if the oil boiler is unavailable or does not need to operate fully. (mistralboilers.com)

Mistral Mega Combi Plus Models

The non-condensing Mega Combi Plus range consists of three models:

Mistral identifies the MC5 PLUS, MC6 PLUS and MC7 PLUS models as exclusive to Mistral. (mistralboilers.com)

Large-Capacity Oil Combi Boiler

The Mega Combi Plus is designed for applications requiring substantially more heating capacity than a typical domestic oil combi boiler.

With outputs extending to 70kW, it is suited to larger properties and demanding heating installations where both central heating and domestic hot water need to be supplied from a high-capacity oil appliance.

Mistral specifically describes its Mega Combi range as providing heating and instant domestic hot water for larger installations such as barn conversions and country houses, as well as commercial-type businesses. (mistralboilers.com)

Integral Electric Immersion Backup

The defining feature of the Mega Combi Plus is its integrated electric backup.

A 230V immersion heater is installed within the boiler’s hot-water store. If the oil supply is unavailable, or if the oil burner is not required to operate fully, the immersion heater can provide a backup source of domestic hot water.

This gives the Mega Combi Plus an additional level of hot-water resilience compared with a standard non-condensing Mega Combi boiler. (mistralboilers.com)

7-Day Programmer

The Mega Combi Plus is also supplied with a 7-day programmer capable of selecting two individual daily time zones.

This allows heating and hot-water operation to be scheduled around the property’s daily requirements and provides greater control over operating periods.

Instant Domestic Hot Water

The Mega Combi Plus is a combination boiler, so it is designed to provide both central heating and domestic hot water from the same appliance.

The high-capacity Mega Combi design is capable of supplying up to approximately 35 litres per minute, depending on configuration and operating conditions. (mistralboilers.com)

The XXL-B water class reflects its high domestic-hot-water capacity and makes the Mega Combi Plus particularly relevant to larger properties with substantial hot-water requirements.

Non-Condensing Standard-Efficiency Design

This particular product is the non-condensing version of the Mistral Mega Combi Plus.

It has a B heat class, distinguishing it from the separate Mega Combi Plus Condensing range, which Mistral lists with an A heat class. (mistralboilers.com)

For SEO and product accuracy, this page should therefore consistently use terms such as:

• Non-condensing oil boiler
• Standard-efficiency oil boiler
• Oil-fired combi boiler
• Mistral Mega Combi Plus
• 41–70kW oil boiler

It should not be marketed as an A-rated condensing boiler.

Large Double-Width Cabinet

The Mega Combi Plus uses a double-width high-quality white casing supplied in two sections to make handling easier.

The cabinet measures approximately 1230mm high × 1100mm wide × 755mm deep across all three Mega Combi Plus models. Each model has a published weight of approximately 380kg. (mistralboilers.com)

The large cabinet provides the space required for the high-capacity heating and domestic-hot-water components while retaining front servicing access.

Installation and Servicing Features

Mistral’s Mega Combi range includes several features designed to simplify installation and maintenance:

• Front servicing access
• Multi-directional flue outlet
• Pre-punched pipe entry points
• Pipe access through the sides and rear
• Removable front casing
• Conventional or balanced flue options
• Suitable for larger heating installations
• Can be used in tandem operations
• High-quality white casing
• 7-day programmer

The manufacturer states that the removable front casing provides easier access for commissioning and future servicing, while pre-punched pipe-entry points help simplify installation fit-up. (mistralboilers.com)

Mistral Mega Combi Plus for Large Properties

The Mega Combi Plus is particularly suitable where a standard domestic oil boiler does not provide sufficient capacity.

Potential applications include:

• Large detached homes
• Country houses
• Barn conversions
• Large residential properties
• Guest accommodation
• Selected commercial premises
• Large heating and hot-water installations

The correct output should always be selected based on the calculated heat loss, domestic-hot-water requirements and the design of the complete heating system.
