The Problem
Ever felt overwhelmed choosing and managing a heating system? Worried about hidden issues like low inlet-outlet delta temperatures tanking your heat pump’s efficiency, pressure problems, or tiny errors causing total shutdowns?
Do you feel a lack of essential knowledge and find yourself overly dependent on installers?
Do you feel trapped by confusing marketing from heating companies, often pushing overpriced equipment or unnecessary services?
Are you tired of high energy bills? Frustrated with inconsistent temperatures and cold spots? Concerned with optimal heating of pools?
Do you worry about your heating system failing in the middle of winter, especially with the risk of water freezing in your pipes?
Are you concerned about preparing your property for temporary absence, particularly during the winter months?
OptiHeatX solves these problems. We offer a fundamentally different approach, putting you in control.
The OptiHeatX Solution
Approach installers fully equipped by OptiHeatX. You’ll have:
- Essential knowledge from the lightbulb Fundamentals and school Design Guide.
- Exact piping and wiring schemes from your customized staged book Design Project.
- Optimally purchased equipment and materials based on clear specifications from your book Design Project.
This comprehensive preparation puts you firmly in the driver’s seat of your heating system project, giving you full control.
Develop your system stage by stage, at your own pace, using the clear rationale provided in your customized map Investment Road Map.
Conclude optimal and safe contracts with installers, using your book Design Project as the definitive guide. Alternatively, perform all or part of the installation job yourself using the comprehensive DIY module in our school Design Guide!
Finally, get cutting-edge smart settingssettings_remote Automation for your heating system. It will automatically perform most acceptance tests, handle ongoing proactive maintenance, and even manage minor error handling.
And if you ever get stuck or need clarification on any aspect of heating system design, our expert-level technical support is always available to provide assistance.
With OptiHeatX, you can do the job for yourself, your friends, or your neighborhood. You might even become an installer with cutting-edge Hybrid Design and Automation experience!
OptiHeatX is a game changer. It puts you, the property owner, in charge. You’ll have all the essential knowledge, detailed plans, and specs needed to confidently buy the right equipment and materials at the best prices. Use the book Project documentation to get clear bids from installers, ensuring fair comparisons and great value. With OptiHeatX, you can slash your heating bills, enjoy consistent comfort, and have a resilient system protecting your property. Direct procurement of materials based on our specs often leads to significant savings. This transparency fosters fairer competition, typically resulting in lower overall project costs and higher installation quality, verified through clear contracts and acceptance tests.
We’re totally independent - no ties to manufacturers or installers. Our advice? Purely based on solid engineering, physics, economics, and what makes sense for your wallet and your property. We arm you with the knowledge (school Guide, lightbulb Fundamentals) and tools (book Project, map Road Map) to make smart decisions, unlike the usual industry marketing games. Plus, our support delivers expert help whenever you need it. This means fair competition among service providers and better value for you.
True optimality, resilience, flexibility and versatility come from combining options smartly. We design truly integrated hybrid systems (multiple water heaters working together in a single heating circuit – see Why OptiHeatX), not just connecting different boxes like many others do. This principle extends to our product stack (supporting staged development), function set (heating, DHW, pools), job source (installer/DIY), our unique DIY Hybrid water heater (Solar Thermal / AC / Solar DC), and even our settingssettings_remote Automation pricing (flexible connection plus subscription model).
You don’t need to do everything at once! OptiHeatX supports a modular approach. Start basic, expand later as your needs and budget evolve. Your personalized map Road Map shows you how.
We achieve this through smart “single-circuit” design (including the efficient “water-only” option), hybrid integration, smart component choices, DIY options (like our unique water heater), and advanced settingssettings_remote Automation (managing inlet-outlet delta, optimizing low tariffs). “Optimal” = best efficiency/cost for you. “Comfort” = consistent warmth and peace of mind. “Resilient” = built to handle challenges.
Our settingssettings_remote Automation system goes way beyond simple thermostats. It provides smart control, 24/7 monitoring, proactive maintenance, automated troubleshooting, safety features, and recovery, minimizing effort and maximizing peace of mind. It even handles automated acceptance testing!
We give you the knowledge (school Guide) and tools to take charge, whether you DIY (especially with monoblock heat pumps or our DIY heater) or confidently manage an installer using your detailed book Project.

Perspectives on a Well-Designed System

OptiHeatX’s core approach is a game-changer. By deconstructing the value chain and focusing on empowering the property owner with knowledge, they directly address the deepest customer pain point: a lack of control. Their commitment to an independent, physics-first philosophy is the foundation of their credibility. The clear segmentation and tailored licensing for different users demonstrate a profound understanding of the market’s ecosystem.


The product line is brilliantly structured as a customer journey. It begins with education (‘Fundamentals’ & ‘Guide’), moves to strategy (‘Road Map’), and culminates in execution. The ‘Project’ is the critical deliverable—a tangible blueprint that grants control over procurement and installation. But the ultimate value is unlocked by the ‘Automation’ system, which transforms that well-designed physical asset into an intelligent, self-optimizing system that delivers comfort, resilience, and real-world savings 24/7.


The ‘single heating circuit’ philosophy is the key to their truly hybrid approach. Instead of just connecting disparate parts, OptiHeatX creates a single, cohesive system where heat sources are natively integrated. The concept of bi-directional heat exchange between the buffer and boiler tanks is particularly innovative, turning two separate heat stores into one unified, flexible resource. This is systems engineering at its best—simplifying complexity to unlock greater efficiency and functionality.


OptiHeatX’s pricing model is as rationally designed as their heating systems. By intelligently linking cost to tangible factors like local climate and system scale—rather than arbitrary tiers—they ensure the price fairly reflects the value delivered. The model’s structure, which favors a planned, thoughtful approach, demonstrates a commitment to the customer’s long-term success. This isn’t just pricing; it’s a transparent equation for a trustworthy partnership.
