FAQs Why Cost-Effective, Efficient Heating Matters for Irish Garden Rooms Garden room heating Ireland – Garden rooms are no longer summer-only luxuries. They’re offices, therapy rooms, gyms and studios that need steady, comfortable temperatures from October to April. Choosing the right system isn’t just about comfort—poorly matched heaters in outdoor heaters can lead to high bills, uneven warmth, and even condensation issues. The smarter route is to pair the right-sized heater with a well-insulated cabin and sensible controls. Loghouse garden rooms are built for year-round use when specified with proper insulation. If you’re retrofitting heat, it’s worth reviewing your envelope first—floor insulation, airtightness and window seals can reduce running costs significantly. Once the shell is efficient, a modern electric solution (or a compact heat pump for larger rooms) will keep your space welcoming without punishing your wallet. In this guide, we compare the most popular options—EVRad ceramic radiators, infrared panels, air-to-air heat pumps, electric underfloor heating, and portable oil-filled/fan heaters—with practical advice on costs, sizing, and controls. Before You Heat: Insulation & Draught Control The building structure serves as the foundation for achieving heating performance in outdoor heaters. The performance of infrared heaters depends on the ability of your cabin to retain heat because they become less effective when heat escapes through floor gaps and wall openings. Prioritise: Floor insulation: A high-return upgrade—warm feet, lower wattage needed. Wall & roof insulation: Specify insulated Loghouse cabins or consider retrofits in older builds. Airtightness: Seal obvious gaps, especially around doors, windows and service penetrations. Glazing: Double glazing with good seals limits radiant losses and draughts. Tip: Fix the envelope first. You can often downsize the heater, improving comfort and cutting running costs. Comparing Heating Options for Garden Rooms Each system below can work well if correctly sized and controlled. Your choice depends on room size, how often you use the space, speed of warm-up required and whether you want summer cooling.

Explore EVRad Ceramic Radiators → 2. Infrared Panel Heaters Infrared heaters emit radiant energy that warms objects and people directly, rather than heating air. This creates an immediate sensation of warmth and works well in well-insulated, smaller spaces. Typical running cost: €0.30–€0.50 per hour for 0.6–1.0 kW panels. Controls: Basic on/off or thermostat; some offer remote control. Sizing: 0.6–0.8 kW for small spaces; position above work areas or seating. Comfort: Instant warmth where needed; less effective if under-sized room-wide. Maintenance: Wipe panels occasionally to maintain efficiency. Best for minimalist interiors and well-insulated studios where instant radiant warmth suits the usage pattern. Controls & Smart Scheduling Good controls can reduce energy use without sacrificing comfort. At a minimum, specify a reliable thermostat; ideally add week-based schedules and, for remote offices, app control. Thermostats: Maintain steady temperatures to prevent overshoot and condensation. Timers & schedules: Preheat 30–60 minutes before use; set setback temps when unoccupied. Zones: Large cabins benefit from two smaller heaters on separate thermostats for even heat. Smart plugs: Useful for occasional heaters; ensure they’re rated for the load. Sizing Your Heater (Quick Guide) A simple way to ballpark sizing is by room area and insulation quality. This is guidance only—Loghouse can size precisely during a quote. Room Size (m²) Good Insulation Average Insulation Poor Insulation 10–15 0.6–0.8 kW 0.8–1.0 kW 1.2 kW+ 16–25 0.8–1.2 kW 1.2–1.6 kW 1.8 kW+ 26–35 1.6–2.0 kW 2.0–2.5 kW 3.0 kW+ Rule of thumb only. South/west glazing, usage pattern and airtightness all influence final selection. Condensation & Ventilation Warm air holds moisture. Water condenses when it touches cold surfaces, appearing on windows and corners. Heating provides benefits, but ventilation systems must operate for complete effectiveness. Background heat: Operation at typical winter temperatures prevents cold-soak damage. Ventilation: Trickle vents or periodic airing keep humidity in check. Placement: Built-ins should include minimal gaps to enable air movement between the structure and external walls. Practical Scenarios & Case Examples Small Home Office (12 m², daily use) A single EVRad 0.8–1.0 kW with a 7-day schedule keeps the space comfortable from 8am–6pm. Set a 17–18°C setback overnight to prevent cold-soak and morning condensation. Creative Studio (20 m², intermittent) One infrared panel placed above the work area provides immediate radiant warmth. Add a small convector/EVRad if you need broader comfort for visitors. Multi-Use Family Room (28 m², year-round) A compact air-to-air heat pump offers fast warm-up, low running costs and summer cooling—ideal for active spaces used evenings and weekends. Yoga Space with Barefoot Comfort (18 m²) Electric underfloor heating on a timer delivers even comfort. Pair with a small EVRad or infrared panel for quick boosts on very cold mornings. Energy-Saving Tips Install programmable thermostats and 7-day timers to prevent overheating. This gives you complete control over when your heating operates based on your daily routine. Adequate insulation maintains warmth while keeping energy costs manageable. Floor and wall insulation improves thermal performance, leading to better comfort throughout the year. Seal entry points around doors and windows, then add heavy curtains to contain warm air. These weatherproofing measures reduce heat loss and lower heating expenses. A small photovoltaic array can offset electricity usage, providing an eco-friendly way to power your heating during peak sun hours. Keep heater vents and sensors free from dust. Regular maintenance ensures optimal airflow and allows sensors to function accurately, helping your system operate efficiently. Buying & Installation Checklist Measure your space while thinking about its position in relation to your entire house. Which direction does it face? How well insulated are the walls? These factors significantly influence what heating solution will work best. Consider the speed at which you need your space to heat. Infrared heaters and heat pumps deliver fast heat output for those wanting immediate warmth. Electric radiators and underfloor heating require longer to warm up but produce continuous heat output after activation. Check your home’s electrical power rating before deciding. The installation process requires specific properties which not all systems can support. Plan cable placement for organized cable management that prevents visible exposure. You have options for temperature control. Units with integrated controls stay simple, wall-mounted thermostats let you control temperature from one location, and smart apps provide full remote access. Finally, don’t overlook moisture. Heating dries rooms quickly, so ensure adequate ventilation—whether by occasionally opening windows or installing trickle vents. This is more important than many realize.
