Every church is different, from centuries-old stone chapels to contemporary community spaces. Yet they all share one challenge: staying warm efficiently, respectfully, and sustainably.

That’s why we created ARCAngel - a complete suite of infrared heating products designed specifically for churches. Developed through years of feedback from dioceses, church wardens, architects, and installers, ARCAngel recognises that one size does not fit all.

Rather than a single product, it’s a carefully balanced system of solutions - each designed to meet the varied needs of worship areas, naves, vestries, and halls. Together, they provide gentle, reliable warmth that protects your building and serves your congregation.

A complete suite of eleven products

From discreet under-pew heaters to dual-purpose comfort systems, every part of ARCAngel is engineered for the unique demands of churches and heritage spaces.

Designed with churches in mind

Developed through years of collaboration with dioceses, wardens, and heritage specialists which has been tailored to protect fabric, improve comfort, and simplify operation.

Infrared and electric heating solutions

A range of efficient technologies from precision infrared to hybrid and combined systems that deliver warmth where it’s needed while supporting Net Zero goals.

Flexible and future-ready

With options including FIRE+ICE and DUO PLUS, ARCAngel offers complete electric comfort: heating, cooling, zoning, and solar-ready performance.

Creating comfortable, peaceful spaces for worship and community.

Traditional church heating systems fail.

Churches are often beautiful, complex, and energy-intensive buildings to heat.

High ceilings, draughty doors, and irregular use mean traditional ambient heating systems are costly and inefficient to run.

Infrared heating offers an unobtrusive, cost-effective, and direct way to keep congregations comfortable while respecting architectural integrity.

Sound familiar? Get in touch with us for advice

High ceilings waste energy

The warm air from a convection system rises up towards the ceiling, above the occupied zone where it is needed.

Heritage risks

Radiators and blown air systems can damage plaster, wood, and stone by heating too fast.

Costly to run

Gas and oil boilers are inefficient and expensive to maintain.

Poor thermal comfort

Traditional convection systems do not provide an even heat distribution, leading to 'cold spots'

Inflexible

Heating the whole church, even when only a small area is in use.

Old wiring or building fabric

Old wiring or building fabric can limit installation options

Why ARCAngel Works

Churches present unique heating challenges - from tall ceilings and draughty stone walls to limited weekday use. ARCAngel addresses each of these with precision-engineered infrared systems that warm people and surfaces directly, not the air.

Each system is designed to work in harmony with the building’s fabric, creating comfortable, peaceful spaces for worship, community, and reflection - even in the coldest months.

Supporting Your Church’s Goals

Heating choices in places of worship are about more than comfort. They reflect care for the building, stewardship of resources, and a commitment to the future.

With ARCAngel, you can:

Support diocesan Net Zero 2030 targets

Reduce running costs with efficient electric heating

Protect the building’s heritage while improving comfort for worshippers

Receive expert guidance on DAC approvals and funding pathways

ARC Thermal works closely with churches across the UK - providing tailored design, technical drawings, and installation support that respect both fabric and function.

Designed for real church budgets and timelines

Most church projects happen in stages - often over several years and depend on a mix of internal giving, grants, reserves, and community support.

Heating shouldn’t be the barrier that slows wider plans.

ARCAngel can be installed in phases to match your fundraising and governance cycle. Whether you're exploring ideas, preparing a feasibility study, or planning a larger reordering, we provide clear, costed options that fit your timeline.

Our goal is to equip your PCC with the information it needs to move forward with confidence.

Support for funding & approvals

Heating is often just one part of a wider building or Net Zero project. We help churches prepare the information needed for PCC decisions, DAC conversations, and funding applications - removing uncertainty at every step.

It’s all designed to help you present a clear, credible case -whether you’re applying for grants or planning internal fundraising.

This support includes:

Tailored heat-loss calculations

Layout drawings and zoning plans

Running-cost estimates

Phased installation options

Straightforward technical documentation

A partner, not a push

We understand the weight of stewardship, funding constraints, and the fear of “getting it wrong.” Our role isn’t to upsell or rush you. It’s to guide your church through choices safely, respectfully, and transparently - at a pace that suits your congregation and your plans.

Testimonials

Fan heaters had to be switched off during mass because of the noise … As the space was used more often, we needed something reliable and discreet that could warm both the air and the building fabric…ARC supported us throughout the approval process with the Westminster Diocese Historic Churches Committee…They provided all the information needed to confirm that infrared heating would have minimal impact on the building…The installation was well planned by Damian Deen. The team left the chapel spotless once the job was complete…The process from survey to installation and commissioning was straightforward, and the units work extremely well.

Each project begins with understanding your space - from the layout and materials to patterns of use - ensuring that every watt of heat goes exactly where it’s needed.

Yes. Infrared heats people and objects directly, not the air, so warmth is felt even in large draughty spaces.

Absolutely. Infrared provides gentle, radiant heat that avoids damaging rapid temperature swings. Products like SolaMagic and EXO Dark are discreet and sympathetic to historic fabric.

Running costs vary, but zoning and smart controls mean you only heat the spaces in use. Many churches save up to 50% compared with traditional systems.

Yes. As an all-electric system, ARCAngel integrates perfectly with solar PV to further cut costs and emissions.

Minimal. Infrared panels and under-pew heaters require no pipework or ducting, making them ideal for sensitive heritage buildings.

Infrared and electric panels have no moving parts and require virtually no maintenance, offering a service life measured in decades.

Just exploring options?

If your project is in its early stages, we can provide an outline plan, answer key questions, and help you understand what a phased heating approach might look like - even if installation is years away.
